Fujikura shaft stiffness, CPM for real

[pettybone3]

I have been trying to decide on a shaft for my X-drive head. I ahve been looking at the Fuji rombax 6xo5. Their cpm advertised for regular is 262 with 2.2 or so torque rating and 276 I think for stiff. Are they really that stiff or am I missing something?

Where did you see the cpm listed? Firstly the torque rating for 6x05 is 3.4 on the US site and if you see the cpm on a Japanese language site, you have to discount by approx. at least 10-15 cycles due to 7 inch clamp. I have a shaft/club tested in Japan and the cpm was 268 and retested using a 5 inch clamp, the cpm was 252. I suspect the 6x05 S would be in the range of 250 to 260 for a 45" 200g head.

I don't think they play as stiff as you would think just by looking at those CPMs. I never put much stock in CPMs since there are different methods for measuring. I've had the 6X07 in stiff flex and it was softer than I expected.

For what it is worth, just checked a Japanese site and it listed a X Drive installation with 6x05 S. While it did not specify which x drive head, the head weight is 195 g at 45", sw is D2.5 and total weight is 319g with a 50 g grip. The CPM is 262 on a 7 inch clamp. BTW, Fuji Japan lists the torque as 3.3 for 6x05.
