What lubricant were you using and what was the overall reductions in your drive system (including wheel size)?
IMO our 2014 robot put it's 3 CIM Ball shifters through far more abuse than the average team and the gears still look as good as new. For that matter, I've yet to see so much as a chipped tooth on any of the over 75 various Vex Pro gears we've used on competition robots in the past two years.

Good catch, not sure how I missed that, I did look at the page. Still getting used to the new AM site layout I guess.

True the difference is smaller in certain configurations, but still less regardless, and Sonic Shifters doesn't really offer anything the Ball Shifters don't also (save a few gear ratios perhaps), so if you can still save some money and weight, why not?
