I've got some friends with awesome kits that I've talked into letting me borrow for about a week at a time to play around with heads and sample the kits. Since a lot of them are going to have the same sizes (esp snare/kick), I'm hoping to save some cash by re-using heads, but I'm wondering if that's at all kosher. Is there something about stretching the head over the shell that makes it tonally unusable on other drums compared to a brand new head? The things are only going to be smacked 30-50 times for sampling purposes, so I'm hoping I can reuse them once or twice!
