I went from Tsi3 to Tsr3 to GT3 to GT2. GT3 was great on perfect shots, longer than the previous 2 gens, but I found the new forward weight configuration too difficult to control the face. Bad shots were SOOOO bad. No spin duck hooks or super spin slices. So I reverted to a GT2 and couldn’t be happier. GT2 is like a TSR 2.75 in my opinion. If you run your Tsi3 in neutral weight configuration, I highly advise you look at GT2. It’s really that good.
