JohnBull that is some serious gearing you have their. Your track must be pretty flowing and somewhat on the larger size.
The 33/104 on our track is good as it is kinda small with alot of hairpins. I normally run 26.50 to 28.50mm or rollout on our track.
I think I will put my one way in again as I check over it last night and just can't find any problems with it. It spins smooth and has no binding. Nothing looks bent so I will put it in again when I know I'm going to a large flowing track.
