ok, I'll order 22 / 78 like you have an give it a go.
regarding the gearbox, I'll have to inspect it for wear then shortly and see how it's coping / possibly swap to the kevlar one. Is it also worth getting a team c kevlar spur?
somebody else recommended the alloy 28t gear as they where stripping plastic ones and had been OK since but if it wears out the other plastic ones then It's a false economy isn't it.
