Timing improved, short balls needed more practice (for me to get the same "pounce on the short ball" thing going again)...BUT one word of caution. For most of us, the heavier weight is compensating for bad technique - i.e. most of us are throwing our hands at the ball, instead of playing the ball under our eyes, WITH OUR HEAD OVER OUR BENT FRONT KNEE, GOING "IN TO" THE BALL.
I also realized that initially, I lost my shape a lot more, with the bottom hand taking over the heavier bat, but a few one handed drills sorted this out.
