Fixed. Everything else is typically the opposite, in my experience with an average of 8 FTC teams a year. With TETRIX there as many or more failure modes than there are for VEX. With TETRIX, the students do all of their own wiring, which is a liability nightmare without the proper guidance. Motors & servos are pretty easy to break or burn out in TETRIX. Metal is, well, metal.

VEX even solves the 12-tooth plastic gear breakage by offering a better, metal one. Maybe we can get JVN to respond for whether it'll ever be an option, but it seems like socket heads rather than button heads would resolve the bolt-stripping issue to an extent? If it's a non-competitive environment the OP may be able to just purchase the #4 bolts from a hardware store. Off the top of my head I don't know what's allowed in VRC though.
