I just ordered a 9* Max K from my local fitter. Going to drop a Diamana WB 53 in it and see how it goes. I am currently hitting the Callaway Elyte with a WB 43x, but I think the 53 stiff might be a better fit as the 43x feels a bit too tip stiif on days the swing is not quite there. I really liked the Ping 10k, but I hit it a bit too high with a little too much spin....hoping I see a little less spin with a little lower ball flight out of the Cobra Max K. For the record, the Ping 10k was longer and straighter than the Elyte, I just hit it (10k) too high.
