Correct me if I'm wrong, but I think this precludes your second alternative. You are correct though, with the CVs we're allowed, large pneumatic cylinders are quite slow for this application. Small ones likely are too, depending on the range you're looking at. I won't say it's impossible, and there are ways to speed things up. Any team looking at this should do the math and test thoroughly, or you may be sorely disappointed painfully late in the season.

In the past, teams have used pneumatics (and cams, and countless other systems) to [edit]arm[/edit] such linear punches, but used springs/surgical tubing/etc to transfer the actual force, as they're so much faster.
