While this frame appears to be in the "Tweener" class it is very much a lower power frame with a 18 x 19 string pattern. It is the 3rd or 4th generation of the Head Ti. Heat. You really have to swing out with this frame to generate pop, but the frame has great control. Flex is 62 and beam is 22 mm.. and weighs 10.4.. 10.6 oz with even balance. I was thinking a full bed of OG 17 @ 58 or so.. or a nice multi.. I think X-1 would also be a nice set-up @ 60. The frame is really a light weight players frame.. L3 swing type Ideas? Thanks..
