Which threadlock for SRAM crank bolt?

Lumen

After switching cranks a lot, I need some more threadlock for my SRAM crank bolt (the smaller inner one).

Which loctite should I buy?

List here.

Where to buy online or in Dublin? I've bought from ebay before, but it took a while. No great rush, just don't want to be waiting weeks.

Ive bought threadlock in Lenihans in Capel St it was part of some glue manufacturers (I think Loctite) display, or otherwise it can be got in most motor factors in the city.

Lumen there is no easy way to go about this other than checking all the data sheets to see which is the lightest. Loctite 221 and 242 are both 1.0800 g/cm^3. Loctite 2400 does not have a density listed (typical!). I haven't gone through the others. Buy in haste, repent at leisure as they say!
