I purchased the XCG6 Driver, 10.5 degree back in May and am really happy with it. I'm pretty particular about my equipment and had been playing the TM Burner TP 2.0. Was fitted for the prior driver and, for the sake of a few extra yards, ditched the lousy TM stock stiff shafts for a Mitsubishi. Went to the fitter this time around (old driver in hand for comparison purposes) fully expecting walking out with the R1 or the Ping G25. Long story short, I hit all the usual suspects and tried all sorts of shaft variations, and the #s weren't all that compelling (i.e., I wasn't gaining much from my old driver). Then the guy through the XCG6 in my hand saying he'd gotten really great feedback from those people who were willing to give it a try. Was a little suspect at first, but looked good from the top and really liked the weighting with the stock Matrix HD6.1 shaft. Sure enough, hit a few and saw improved numbers. Was really surprised. Almost thought the guy was tampering with the machine. Then did a bit of adjusting with the wrench and the numbers improved even more. Had the fitter trim an inch off the end of the shaft, #s stayed the same and whereas I expected to drop around $500+ on one of the big name drivers, I walked out only @$300 lighter in the wallet.
Have been playing all summer with it and it's not disappointed me (although had to get rid of the hideous headcover).
