My stringer is an Alpha Pioneer DC+ dropweight with a 6 point mount and fixed clamps. The racquets are the Dunlop MuscleWeave 200G 95 and the Dunlop Biomimetic 200. Both have oval shaped heads. I've noticed that while I'm tensioning the crosses in the bottom half of the hoop, the lower side mounts nearest the bridge become loose. And the frame makes a straining sound which could be graphite fibers breaking. To avoid this, I was wondering if I should mount the racquet a little lower, to fill up the lower side contact points better. I'm thinking of only a 1/16" fudge from center. If not, what would be a better approach? Thanks in advance.
