Hi everyone, This is the first time I'm posting in the string forum. I've been on the message boards for a while but mostly just for selling racquets. Anyways, it looks like guy/poly for the Wilson BLX 90 frame is supposed to be the cream of the crop setup for this racquet, but at the same time, whether it's cost-effective is another story. I was thinking of trying Technifibre NRG2 mains with MSV Co Focus crosses. Does anyone have any experience with this particular setup and if not, does anyone have any good suggestions for a multi/poly blend for this racquet that I should try? Thanks for your help, seems like we have quite a few people on this board that have a lot of insight.
