I have the M on one of my shafts and really like it. I usually shoot with a Morri M and it has a very similar feel. I'm going to take Tom Hay up on his summer sale and mix up the different ones.
All the tips play good imo. I prefer the S cut down and I also break with my player at first to get it settled real good. My 3 cushion friends all play with HH or some with H and they think it´s the best tip out there by far.
I personally play with a solid maple shaft and a ordinary ferrule (no LD) and like the hit to be firm, sound and feedback is increased imo.
If I would play with a Pred shaft I most likely would put a H on it so I felt more accustomed to the hit of my preference.
