I recently bought a 2017 M1 head online thinking it would fit my old Taylormade driver shaft but it doesn't so now I'm trying to find one. I know absolutely nothing about shafts so I'm looking for some help since there seems to be a million options. I'll tell you what I do know about my swing and maybe someone can tell me what to buy. I swing 120+ plus but I hit the ball really low and I always have...so I know I need x stiff and maybe something that will help to raise the launch angle since I must be too steep at attack. I went to our local golf store yesterday to hit a few and he was saying that I put a lot of spin on the ball and I'm sure that is a result of my angle of attack. I don't need the latest and greatest shaft just something decent that I can play with and I don't mind buying a used shaft... Any help would be greatly appreciated... Thanks
