Any of these should work

I have the small and the medium and they're great. Brake levers are simple and I doubt one will work better than the next but these are built really tough. They sure don't feel light compared to cross levers, these are heavy and durable. BTW the small is a 2 finger lever and the medium is 3 fingers just so you can gauge how big they are.
