I just bought a Sonartec NP-99 off ebay today and have the option to get either the 75R/S or 75S shaft (Aldila NV made for Sonartec). I am not sure which one to go with. I have a few questions and I would appreciate any answers and/or imput. Is the Aldila NV in the sonartec the same exact ones from aldila with just a different paint job (ie. will the 75S in the NP-99 play the same as a 75S from aldila directly)? Second, anyone with experience with either of these shafts I would like imput on how you feel they play and comparisons to other shafts/flexs (what would your flex be equal to in say a YS-7 for example). And my last question: my swing speed with my driver is about 103 MPH with a smooth tempo, I play a stock TP 757 Stiff flex in my 510TP and a YS-7 Stiff flex in my Sonartec SS-02 4 wood and Callaway Steelhead Plus 3wood (YS-7 Stiff)...based on that information which would you recomend (75R/S or 75S). By the way the shafts in my driver and fairway woods work great for me (the flex is good.

Any information would be greatly appreciated and I need it ASAP also...please get back to me as soon as possible and thank you soooo much in advance!!!

The only thing I know about this is that the NV is supposed to be the same as a regular NV. Good luck.
