The Tour Green NXT 75 X is almost identical to the NV 2KXV 75 X. Weight is within one gram, torsional stiffness is within .2 degrees (unnoticeable) and they are both low/mid trajectory shafts with the same MPF rating. If they wre both painted black and you were testing, you wouldn’t be able to tell the difference. I didn’t put them both in the Club Builder as an option because they are so similar. If you want the 2KXV, you can call your order in and we can build it with the NV 2KXV, no problem. I do think the Tour Green NXT GEN will work just fine.
