We used a 2 speed ball lock shifter last season and thought it worked out great. Assembly was a little annoying until we figured out that using grease to hold the balls in place while sliding the parts together works very well!

We also just built the plunger as 1 piece instead of using springs. This seemed to work pretty well because the air in the cylinder basically acts as your spring. I had the rookie kids this year pull apart the gearboxes to "get their feet wet" plus I wanted to see what they looked after a full season. The insides held up even better than I would have thought. The plunger definitely showed lots of tiny "dings" but is far from failure. We put it all back together and it still works great.
