That's a great question as I had the same question before joining Callaway. I really liked the TSI and still believe it's Titleists best driver since 975D. Without a shadow of a doubt, the Epic '21's are faster across the board. I hate using "better" ever these days but after testing head to head Epic Speed had faster ball speed out of the middle and id say they are apples to apples on mis-hits. Gotta get fit, try them both. The other thing I noticed in comparison was TSI was an easier driver to fade than MAX LS but MAX LS does have that GOOFY LONG BALL built in it that the TSi doesn't in my experience. You know that 13 launch at 1800 spin thing?Has anyone hit this against the TSi3? Curious how they compare for a fast swing speed.
Once again it's not about what is better but what is best for you. We are talking about the class of 2021 in the driver category. These are the two best heads on the market right now. We are punching hard this year. Very hard.
