Both are very good racquet at that price, get one for each model man, LOL. Basically, you will have to check the specs on the racquets yourself as SOTX measures each racquet individually, find the right weight/ Balance point/ length for yourself.

I got my SF201 today. It is pretty good for $30. If you check the max sport website, the 201 is sold out and there are 13 202 left.
