All characters who carry training weights (goku, gohan, piccolo, krillen) should be able to take them off with a button other than z, available only once per round (map), and raises the PL by 1.2 times their current (perhaps raise speed a couple points), this adds a bit more dbz in, and makes one more thing for pros not to do. It is perfectly possible to have the weights stay on the ground for a few seconds at least (treat them just like bullet shells, this way at least no one will see them disappear) I know this is similar to the "training cape" thread, but I think this works a bit better in practice, as you won't need a certain PL to do it, but most people won't do it right off, because they won't gain much PL if they do it too soon.
(for those not skilled in the ways of math, 1.2 times is a 20% increase in power level, quite a bit for something like this.)
