So the String way/Alpha clamps are out of the question due to their high cost, but I've got to get rid of these bulky plastic Prince/Gamma clamps. I'm trying to decide whether to buy the Klippermate or SP Floating Clamps. It sounds like (correct me if I'm wrong) that they're both all metal construction and grip/resist slippage equally well. I'll mainly be stringing one-piece, ATW patterns. But which clamp is really better? Which is easier for one handed operation? (Both for clamping and unclamping) Does one require more clamping force to close/open? Thanks!
