Comments: I probably should describe myself first. I am in my mid 40s, men's 4.0 with decent record of 19-4, and I play mostly doubles. I had wrist and elbow issues and have ongoing shoulder issues. I can slice but rather belt the ball. I have a 110 mph flat serve, but mostly will kick or slice serve. I have tried Luxilon Big Banger TiMO, Rough, Ace, Wilson NXT, and Tecnifibre NRG. I liked them all. However, I now prefer Wilson Enduro 18 for my mains. It is a thinner gauge - more spin (may be psychological), but feels easier on the arm. It feels reasonable feel at net. I was pleasantly surprised by durability (so far 8 hours without even fraying).

Comments: Durability is good in 18 gauge category. Spin potential is as expected from this type of string (very good). Power level is in right range. Feel is ok, no complains. Overall is very decent quality.
