I am looking to use one of these shafts . I was also thinking of using the project x. My swing speed is +- 100 mph.I am looking for a shaft that will help get th ball up, and something that will have a soft but solid feel. Thanx in advance. :?

I don't know the Nippon but have used the Flighted Rifle and the PX in my irons and demo'd plenty of DGs. My SS with the driver is ~95+.

"Soft but solid feel that helps get the ball up (with the mid and long irons)" perfectly describes the Flighted Rifle. If you have a nice crisp release (no blocking or dragging), you might like the PX but it is a little harsh for some and gives a lower, flatter trajectory than the Flighted Rifle. I prefer the PX because I get plenty of height with my irons.

The DG will be harsher and fly lower than the Flighted Rifle.

You probably shouldn't go over 5.5 with the Flighted Rifle or 5.0 with the PX.

i would say the nippon has a solid soft feel hit higher and something you can hardstep or just get stiffer that wont hinder its superior performance.
