We went to 3 regionals this year and wore through 5 20T VexPro gears with our 3rd stage of Ballshifters. We ended up switching to the Andymark steel gears (broached hex). At the end of our Idaho regional, our 64T VexPro gears were trashed, luckily we had replacements for those.

Some of our issues were due to the lack of securing the 3rd stage to the BallShifter. We were having a lot of binding when we tightened the 3rd stage too much, so we tried to find a happy medium between too loose and too tight, we think this caused some issues with gear tooth engagement when it experience shock loading.

This year was rough on drive trains.
