not sure exactly where to post this... I'm experiencing a strange problem with the kilppermate. When I string the crosses (never the mains, though I use a synthetic gut in the crosses and a poly in the mains), the drop weight and grip will often reach balance, and then abruptly dip down. When I remove the string from the clamp, it has been flattened out and stretched (hard to explain, I hope you can visualize this...). It doesn't *appear* to affect the life of the string or playability, but it is making stringing a hassle. I don't think I'm bruising the string with overly tight clamps... has anyone experienced this with a drop weight? any idea what to do about it?thanks for any advice.
