We'll also be using them this year, so here's some info I know about them.

The ratios should depend on the game. You don't want to gear for really fast if the game doesn't require a lot of speed, and likewise, you don't want to have a really slow gear if you don't need to push anything.

Personally, I'd choose the pneumatic shifting, as it allows for shifting on the fly, and can be a lot better in some situations than servos (Such as shifting while going at full speed).

We, too, plan on using 1114's Kitbot on Steroids this year, with AM SuperShifters, so if you have any questions on it, feel free to contact us or PM me!
