I am looking to upgrade my Gamma X-2 and have been looking at the SP Maestro, Alpha Revo 4000 and the Gamma 5003. My problem is that in addition to tennis rackets, I need to be able to string squash rackets, in particular Prince fan pattern rackets like the O3 Tour that have a unique throatless design. Will any of the above stringers work with that type of squash racket? I am worried mainly about 1) the clamps, which I have heard may be too big for squash rackets; 2) the tension range -- I need to be able to go down to 25 lbs; and 3) the mounting system, which may not work on squash rackets and the Prince in particular. Any help you can give me would be much appreicated! Thanks...
