Thanks for posting all the good info. Here is what I got. I have tune my daughter's racquet (she is 15) for a long time using Travlerajm's method and it seem to work very well. I ended up with 324g with a balance of 32.7 and swingweight of 310. She was using a windsheild style forehand and it seemed that the shots where very spinny but not a lot of power. I tried all kinds of strings and tensions and I could not get any more power out of it. So we changed here swinging style to a Djokovic style swing which took about a month to do. Now that racquet will not work at all. The balls fly all over the place. No control at all. Tried more strings and no luck. So I tried another racquet. It was an nTour Wilson and it has some weird specs so it could be fake I don't know. Well she started hit a little better. So I just started adding lead to the top of the racquet and it got better and better and better. I added 18 grams at 12. So now her shots are controlled with a lot of spin and power. The specs are 314g with a balance of 34 and 337 swingweight. Not really close to the other specs. So I was just trying to figure out what is so different between the two styles of hitting and the curve on the racquet map. Here is a link for some WTA specs.
Look at Sloane Stevens racquet. Thanks again.
