No problem man. You won't see much difference in high but it is more torquey in low. Engagement rpm is a little higher in both gears. Make sure you look at your rollers, mine had flat spots on them and that's why I also ordered the steel ones.
Ya iv head of the composite rollers getting flat spots, iv only got 14 hrs on mine so I shouldn't yet, but ill upgrade to dalton steel rollers probly nxt summer, thnx again
