Id do it myself i see the math is pretty simple i just dont know how to find the balance number in cm....

I got 20.92734649 for the Donnay Gold 99 when I did the math. I used this in Microsoft Excel to get the balance:
=+(((685.58/25.4)/2) 6*0.125)*2.54
The 685.58 is the length (close enough for government work), 6 is the points head light the balance is.
I basically created a little spreadsheet with some rackets and started plugging in data from Tennis Warehouse.
I found several racquets that came in at roughly 21 bone stock using TW data.
Volkl DNX9 (21.01)
Dunlop Bio 200 Plus (20.99)
Head IG Instinct S (20.97)  This is the odd one of the group, as it is very light
Pacific X Force Pro (20.97)
I'm sure there are others, but also in my list for close are the TFight 320, and original TFight 315.
