Currently playing a 6066 in a R5 TP 10.5, and am doing just fine with it. Just got a X-Drive 460 head and wanted to install a similar shaft, just a little lighter so I can get my swing speed up. Normal swing speed for me is 90 - 95 mph, smooth to a little quick tempo so I'm usually between a regular and stiff. Not in any rush to put this together, just checking if anything is available. I live in Hawaii and I can paypal funds.

Just wanted to add Mach Line 5250 or 5040 to the above, though I may just purchase this from this sites pro shop at a later time, as its a bit more reasonable. But if anyone has a used one that they want to part with, let me know.
