My Titleist experiment has ended. Went through a sleeve of L57 and didn't notice much difference compared to the TM L81.
Haven't been playing all that much anyway, so it's a waste for me to spend the extra credits on a ball that isn't that different from the 550 credit balls I'm using.
Your mileage may vary.
I've come to the same conclusion and have decided to stick with the TM Level 81 ball.
A few days ago, I had a couple of bad rounds with it and was thinking of switching. Then over the last couple of days I had some decent (not spectacular) rounds and thought, OK, maybe I'll stick with it.
Tonight, I shot a 27 from the tips on the back 9 of Chambers Bay with a hole in one on 15. I'm thinking the bad rounds I had the other day had nothing to do with the ball. :-)
TM Level 81 is good enough for me as well. No need to spend more credits on "better" balls.
