I live in an Asian city, and they don't carry as many older models as they may do in North America. The store had many Stealth and Stealth 2's (including their variations), but not the Sim2 anymore. There weren't any available in the used section.
I had like 4 rounds of golf in 2 weeks, and so I was kind of desperate to get a new driver, and I just felt like the TSR2 would be a good fit based on what I read and watched, as well as having tried a couple swings previously on the course with a friend's.
The simulator was the same simulator at the same usual spot that I go to, and without a doubt in golf mode.
Unfortunately, I did not really record my launch angle and spin numbers with my SIM2, so full comparison might be tough now.
On the equipment side, besides the head, overall swing weight was lower with the new TSR2 (D2) vs Sim2(D4). But, honestly, when I had my Sim2 at C9, I hit the ball even slightly further. Not sure what the deal is with my new driver.
My typical clubhead speed for both clubs average at around 100-103 range. Top would be like 105/106, and low would be 98ish.
