I have a set of MMT 105’s and am stuck on which head to use. I have a set of TS3’s and Srixon ZXIR HL. Low to mid 80’s 7 iron SS and an aggressive transition. Average tempo is roughly 3.9 (.63 backswing and .16 down swing). I’m 6” with 35” wtf. I will probably soft step the MMT’s in either head

Srixons have KBS Tour Lite R flex I get high almost ballooning shots

TS3’s have MPF pro series r flex. I just can’t hit this combo with any consistency for some reason.

How would a lower height and spin shaft work in a HL head?

I’m worried about low spin with the TS3 head and mmt shafts.

thoughts or suggestions?
