I have never hit one of these shafts so I can not speak from experience about. But I love my Stealth 70s and Ultrons from Penley. I would give it a shot.
I was looking some things up..
Golfsmith has a .335 to .350 converter.

Well.. I took your advice and ordered the Penley Stealth 70 with that converter..
Hopefully it fits me well and I can squeeze out another 20+ yards or so..
Gorgeous shaft Phantom!!
Good call, I got the shaft put on yesterday and took it out on the back 9 of my local public course this afternoon... I was very happy with it..
I have alot more control of it compared to the TM stock shaft.. The stiff flex feels just right snapping through ball.
And this with only 7 swings!.. I can't wait to take it to the range and experiment with it a little.
Thanks for the recommendation.
