I have gone back-and-forth between TSi3 and Rogue ST Max LS for the past 3-4 years, and recently switched to a TSR2..
For me...
The TSi3 is the best looking and longest driver I've ever played, on a good strike. For me it gears too much on off-center hits, once you get too far out on the toe. Not the friendliest club in the world, and wasn't designed to be.
The ST Max LS is significantly more stable, more fairways hit, but a little too much spin and doesn't have the ball speed of the Titleist. It also doesn't want to gear left on a nice slight high toe strike. Starts down the right and stays there. Granted that's probably part of it's "forgiveness" factor, but I do like to see the ball go left a little. It's annoying.
I've been wanting something between those 2, and I might have found it in the TSR2 (10 set at 9.25). So far, it seems to have very similar ball speed and spin to the TSi3, likes to gear left a little, and has much more of the Callaway's overall friendliness on a garbage swing.
I've range & on-course tested a number of different heads over these last few years, and this TSR2 is the only one that's seriously caught my attention. Strangely enough, the GT2 did not seem to work for me. Definitely too much spin when I tested it 6 months ago. Who knows, that's probably just me on that day.
I've only hit the TSR around 100 times, so definitely still honeymoon, but so far I am impressed. It's also a relative bargain right now, and that's always nice.
