i think you might have missed some of the earlier post in the thread drak. some of us have had unpleasant arm experiences with poly. [the last time i put poly mains in my racquet my arm left home for 3 weeks and it took me sending 8 text messages to convince it to come back.] so we are dropping the tension on gut but not as low to see what kind of results we get.
i just got back from hitting about 150 practice balls with this setup (global gut @ 48# & Alu BB @ 44#) and the pop was very nice on flat. I've been nursing golfers elbow as well and the experience was virtually pain free. we will see tonight when i practice ground strokes. so far so good though.
I did not miss anything, I am a guy with a very sensitive shoulder after a not too long ago 8 month rehab from a full rotator cuff tear and other shoulder damage. Poly at low 30's feels better than gut to me FWIW and IMO.
