Anyone thinking of using a past year supershifter should read the following.
A previous generation shift block assembly used a tiny roll pin which we have broken more than once in past years (as a transmission) with a standard 3/4 pneumatic cylinder (ie 24 lbs force). So for example we can't see how that pin could possibly survive the 102 lbs force of a 1.5" cylinder in a winch application.
Our new Super Shifters arrived today (basically free with the use of our PDV) and close inspection of the current shift block shows it is using a captured E Clip which should have many times the shear force strength of the tiny roll pin used before. The "captured" feature should mean the E clip cannot "back off" accidently, it can only shear off under normal operations.

I cant fathom the roll pin breaking unless something was done to it. A standard 1/16 roll pin is rated for 430 lbs of shear. How a 23 lb piston broke that is beyond me. Possibly poor quality roll pins, or damage before/during install? Here is data to back up the numbers.

E clips are rated for more, 600 lb shear strength, and should survive with no issues.

If you want to find someone who has shot a lot of balls, contact either the RI3D guys (they are on this forum) or Andymark, as Andymark is selling the Supershifter winch that the RI3D guys made with Supershifter internals. This uses the stock shift block and shaft assembly.

Hope this helps
