What do you mean "multiple flex points all the way down to 70"? Generally, the more you cut the stiffer the stick will feel, not the opposite, so the longer the stick the lower the flex. Not sure if that's what you mean but that's how it sounds, also your first post mentioned cutting a 95 flex down to the height of an 85 flex, which seemed odd since the height of each would be the same unless one was an extended version.
Either way, if I were in your shoes I'd keep the curve and go with the lower flex. I love the P90TM and have gone back and forth between that and a P28 and the P90TM wins it for me, such a great curve, just wish it were easier to find pro stock and sellers knew the difference between P90TM, P90, and P90T since they're definitely not the same lol.
