First of all, thanks for telling us about the "undefined" thing.

JETCELL! CERRWIDEN! WE GOT STUFF TO FIX!

Look, I would go with the MEGA dart, make the circle 4mm thick and try not to screw everything up.

Also, you got good points: indeed, with craft foam, depending on the type of glue you use, the whole thing will get brittle. Here in Brazil we have a plastic glue made for craft foam, but that could leak and stop the plunger. So, I think it is a no-go.

Let's see what the other guys have to say. I would stick with a 4mm thick MEGA circle and test it. I know it is enough to cushion the impact, but if you have loading problems, you can remove it, cut a new, thinner circle and try again.
