Thanks guys for the input. I'm still trying to decide if it would be best to go to the 18T. Over 70% of my riding is stop and go around town and 50% of that is riding 2 up. We are going on a huge 60 mile bike ride (last year this event had 400 bikers) and maybe it will help me decide. I guess the only time I really feel the need to change is riding over 60 mph, although it would be interesting to see how it effects the shift range overall. I'll probably get the dealer to do it while getting service and use whatever sprocket (brand) they stock.
