Hey I'm moving from 14's to 16's I was top 75 nationally USTA for 14's but I am now just getting outhit in 16's. Im a pretty small kid, about 5.5 100 lbs. My speed and stuff got me through 14's but now it just doesnt work. I will try to get some video up soon but I have a a semi-western, not a huge loop and am having trouble gettin good pace on the ball. Anyone have tips for hitting through. Also, I know I have to get a lot stronger since I am smaller and stuff, but just basic things would help.
