I switched from the made for Ahina to the Ahina 70 and my backspin dropped quite a bit. The launch angle is more of a boring trajectory for me. The Ahina 70 has less torque and feels more solid to me. I also switched out my made for ahina shaft in my 3 wood to the Ahina 80 x5ct and have had the same results. No regrets switching shafts.

It's definitely stiffer with less torque.  One suggestion, with a softer impact on the wallet, would be ordering a Titleist Ahina 72 tipped 1".  That will bring the baseline shaft characters much closer to the unbranded Ahina. 

Thanks for the responses guys.  I'll take both of those options into consideration for sure. 

The real one has a much more stable and lower ballflight with a way better feel
