Put an hour and a half of practice yesterday with the VCORE 97. Just hitting nonstop, not playing sets. Found it a bit heavy for my loopy topspin stokes. Definitely pulling the plug on the 2013 APD and string it with a soft copoly at low tension or with gut/poly.
I will sell both VCORES and also buy a Volkl V1, lead it a bit, and use it as the "rest the arm racket" when the Aeropro gets a bit nasty on my arm.
