G.O.A.T.
Dartagnan64 suggested a similar idea that the added flex of the V7/lower power had me taking bigger cuts at the ball to get the same level of power. On court, I did feel at times I had to be more aggressive to get a similar response with the V7 compared to the V6.
I love 4G for its tensioin maitenence, so if I can get back into my V6's with lower tension 4G and keep tennis elbow at bay, I'll attempt lower tension 4G in the V7s.
Ditch 4G. Put in Velocity, Prince Premier Control or Technifibre Triax and keep the tensions down and focus on hitting smooth with a loose grip.
Once you get to this stage of TE you have to either abstain from tennis or totally soften everything up. You will not get better with any racket with 4G in it.
Take it from someone that has made that mistake not once but twice
