I currently have ProForceV2 Hybrid shafts with the .335″ tip in R flex in a couple of old hybrid clubs that I truly love. I hit them long and straight with a good, medium high trajectory and couldn’t be happier with them. 

I have a couple of other hybrid heads with a .370″ hosel and want to use the same ProForceV2 Hybrid shaft in .370″ in them. 

However, looking at the stiffness specs for the two shafts it appears that the .370″ R flex is stiffer than the .335″ R flex. 

Would the .370″ A flex shaft give me a flex profile closer to the .335″ R flex shaft than the .370 R flex shaft? 

Thanks for your help, 

Jim
