i just had a quick question i have 2 brand new espiritu shafts and when i roll them without the butt, the middle of the shaft lifts up but the tip stays grounded. do cuemakers provide warranties against these imperfections? ive tried contacting espiritu but no answer! the butt is straight alone, but with the shaft put on it has a noticeable roll. is this a taper roll or warpage? thanks in advance.
