I am looking for a K90. I will only consider a 4 3/8 grip size. I have several rackets that I can trade for, or I can just buy it. If you are interested in trading though, I have a FP Radical MP, FP Prestige MP, KFactor 95, and a Babolat Pure Storm (the older one). If interested, email me at leonard . agranat @ gmail.com.
