I've got a lot of history with modding the frames to my liking. My go-to specs a couple of months ago were 350-355SW, 365-380g and 32.8cm balance. Recently however I went back to a much lighter weight beginner racquet with specs 310SW, 310g, 33cm balance. Hitting with the lighter frame initially felt trivial, and back then I played better with it. But recently I've had a lot of timing problems with strokes. I've played very badly and as I watched a video of a practice session in which I played a bit better, it was clear I was arming the strokes. Nice followthrough, but no hip drive or racquet lag, just armswinging. What do you think: Is it really possible to avoid arming with these very light racquets? Or put in another way, is it even possible to hit an ATP style FH with an appropriate racquet lag using a lightweight racquet? Doesn't racquet lag need enough inertia so that racquet naturally "drops" into the lagging position?
