First round in the books with the Sim 2 Max. I like it! I used my current shaft instead of the one that came with it. The head is 204 grams versus 195 for the M4! So at 45.75" on the 60+ gram Kai'li red, the swingweight was D7. And it felt like a sledgehammer. My gamer shaft plays at 44.25 with the M4 lead-taped up to 205, so it was a good match to just put the Sim 2 on it.
It's solid feeling and sounding, and gave me good drives. I'd like to say longer than my M4 but it will take several rounds for me to really know that. It seems to be better on slightly off center hits. Overall the results are better but I can't define why just yet.
@Typhoon Was the Kai'li red a no-upcharge aftermarket shaft, or made for, if you know?
