I have a laserfibre ms200tt. I usually have the clamps pretty tight, because I'm paranoid of clamp slippage, it has no effect on my duraflex. But today I was using tecnifibre e matrix 16, and the string started flattening in the clamps, so I loosened them up...but how loose is too loose? I have trouble telling if there is clamp slippage, but I don't wanna damage my strings... If anyone has any tips for me, please tell me. Thanks, moos.
