I own and regularly play the HP shaft…I’ve got one in kielwood and on in rock maple. Not sure what you’re after, but both of mine are 12.75mm at the tip, the taper is on the money, and the hit is solid. Until recently, I was parlaying LePro tips on these shafts. I just discovered Kami clear tips, and I’m not looking back. Deflection is low, and craftsmanship is quality. I feel Iike you can’t go wrong. That said, I have not played a wide array of low deflection wood shafts, so your mileage may vary, as they say.
