I have a cue (i will not mention name at this time), that has a problem...If i take the butt of the cue and roll it on the table (pool table or kitchen table)the joint and pin lift off the table about a 1/16 of an inch..But when i put the shaft on the cue (either shaft) the cue rolls str8..The cue also sights str8..How can this be? The wrap and butt plate dont seem to come into play...Any ideas? Thanks....Don
