Graphite Shafts

"Flex" refers to the ability of a golf shaft to bend as forces are applied to it during the golf swing.

Those forces are generated by the type of swing that you have - fast or slow, smooth or jerky.

There are five generally used ratings for shaft flex: Extra Stiff, Stiff, Regular, Senior and Ladies, usually denoted by the letters X, S, R, A and L ("A" is used for Senior because this flex was originally called "amateur").

Having a flex that doesn't match the needs of your swing will result in the clubface being misaligned at impact, causing your shots to go off-target.

Shaft flex impacts, either directly or indirectly, the accuracy, trajectory and distance of your shot. Three pretty important things, eh?

As the shaft flexes throughout the swing, the position of the clubhead changes. And the face of the club must be square (perfectly straight) at impact to get the most out of the shot. If you have the wrong flex for your swing, there is less chance that you'll make contact with the ball with the clubface in a square position.

Some General Guidelines

The degree of flex in your club shafts is something you control. You can choose to buy stiffer shafts, or softer shafts, depending on your needs.

But how can you tell what you need? Here are some general guidelines:

• Take a look at the distance you hit your driver. This is a good, but very general, indicator. If you carry you driver 250 yards or more, go with Stiff; 230-250 yards, Regular; 200-230 yards, Senior; less than 200 yards, Ladies. Only the biggest of the big hitters is going to need Extra Stiff. For most of us, Extra Stiff isn't even in the picture.

• If you have a very smooth swing, you might benefit from a softer flex even if you swing very fast. A swing that gets jerky at the top - when transitioning into the downswing - will probably need a stiffer shaft.

• If your drives go left, you might benefit from a stiffer flex; if your drives go right, you might benefit from a softer flex.

If Your Flex Is Too Stiff
What effect does a too-stiff shaft have on your golf game?

1. The ball will probably fly lower and shorter for any given loft, compared to a properly fit shaft.

2. The ball may tend to go to the right, or fade side, for right-handed golfers because with a too-stiff shaft the clubface is harder to square (the clubface is more likely to be open at impact, in other words).

3. The shot may feel less solid, more like a mis-hit even if you make contact on the center of the clubface.

If Your Flex Isn't Stiff Enough
And what will happen if your flex isn't stiff enough?

1. The ball might fly higher for any given loft, compared to a properly fit shaft.

2. The ball may tend to go left, or to the draw side, for a right-handed golfer (because with a too-flexible shaft, the clubhead may tend to come into the ball closed).

3. Shots may tend to feel more solid, even when they aren't.

Macho, Macho Men

Men like to hit Stiff shafts. It's a guy thing. Unfortunately, it's not always the smart thing.

No macho man wants to be seen hitting a wimpy little Regular flex club, or, Tiger Woods forbid, a Senior or Ladies flex.

But overswinging is a common problem among male high-handicappers. Choosing a softer flex often has the effect of forcing macho men to slow down their swings. And slowing down the swing often makes those macho men into better players.

And the fact is, the harm in hitting a shaft that is too flexible is much less than the harm in hitting a shaft that is too stiff. As equipment guru Tom Wishon has said, when unsure about flex, always err on the side of more flex. If you can't decide between Regular and Stiff, go with Regular.

The Foolproof Way to Choose Flex

A club fitting with a golf professional is the recommended way to choose the proper flex.

The pro will take a lot of measurements, watch your swing, measure your swing speed, watch your ball flight and be able to recommend which flex is right for you.

Club fittings are available at many pro shops and almost all golf schools and from teaching professionals.

If a club-fitting isn't in your future, the next best thing is a demo day. At demo days, you'll be able to hit many different types of clubs with different types of shafts.

The key, short of a club fitting, is hitting lots of different clubs and watching the effects on your shots of changing shaft flex.

If you find a flex that feels good and produces a good ball flight, there's a good chance that's the right flex for you.

Pretty good explanations. Most men think they need stiff shafts but unless you can drive well over 250 yards then I'd question that. I usually hit a stiff shaft out to the right when I've not been playing for a while so I agree that hitting straight right is an indicator.


I think my current driver is regular and I carry 250 plus.......I hit the ball very high and with a slight draw with a 9 deg loft. My old driver was a stiff shaft but I prefer the regular even though I should be playing with a stiff. As was said above it's better to have a flexible shaft than a stiff one as with too much flex you have to slow down and swing smoother. I agree that too firm is bad. I'd rather sacrifice a bit of length but swing easier than have to hit the ball hard every drive. Better players can do that but not me.

With your handicap I'd suggest you need a regular shaft unless somebody tells you otherwise. There's no standard for shaft stiffness (as far as I know) so one manufacturers stiff could be another's regular.

Any good pro shop will help you choose (even if you are on a tight budget) so don't be afraid to ask. In fact try several to see if they say the same thing.

34 to 35 points is playing to your handicap.......most people shoot in the high 20s or low 30s and only shoot 36 or better every so often (then they may get cut anyway so that makes it hard to keep shooting 36 plus).


Best way to lower your scores is to get lessons and to practice your short game.

Agree with the "draw" biased drivers. I use a neutral faced driver (Titleist) and if I used one of the draw biased ones then I'd be snap hooking everything. I was considering changing from a regular shaft as I hit the ball high and with a draw but I'll persist for a while as it's controllable.

The golf shop in the new beacon in sandyford has a swing computer, that measures your swing speed and angle etc, and the lads will tell you which shaft suits you best.

What would you pay to upgrade from regular to stiff or extra stiff? Do you know where this can be done or do all golf shops carry out this work. I got a new driver at the start of the season but now was told that regular shaft does not suit me and i need stiff.

Probably would be better off trading in the clubs you got for ones more suited to you. Reshafting is an expensive business if you want it done correctly, and needs to be done right. Fore Golf in Naas would do a good job I would imagine, but your best bet is to try some demos on a driving range with a custom fitter/pro and get advice from there.
