Just went through a fitting yesterday, and improved my numbers over my current TSi3 with both the TSi1 and the TSR3. Actually, both gave me nearly identical numbers, but got to those numbers with different ball flights. I'm wondering, when is the new TSR1 going to be released? The fitter said it will probably be in the spring, but didn't know if there is a firm date yet? Would love to test the TSR1 and TSR3 against each other to see if one turns out to be better.
