We've always used the Gen 1 AM shifters or similar design when using chain as the final drive since we don't need the third gear stage. We used the SS stock to direct drive 6" wheels in 2011 and were happy, with gen 1's in 2010, 2012, and 2013 and were also happy (with the shifters, not necessarily our gear choices). In 2012 we made a cover to keep grease out of the cRio (it was in line with the gears), and removed it before the first competition for weight after the transmission stopped flinging grease. No issues with stuff getting into the gearbox, although we did get a large chunk of ball in a chain in 2012.

I too would like a lower ratio spread option. It's really all about what your gearing objectives are, how you want to play the game, and how open the field is, but I personally would like something on the order of 1.8:1 spread
