Tennis coach here. I prefer Wilson Blade 98s, but I have used Babolat Pure Drive many times and find them more than adequate.
A stringing suggestion if I may... try out Solinco Tour Bite if you want to add a litle more spin and maybe drop the tension a bit. Mine are at 46 lbs.
I will try that next time. Also I think you may be right regarding the tension. 60 is pretty hard on the arms😀
For sure, I also like the additional power from the lower tension... plus I never break my strings!
