I play with a Babolat PCZ360. I am a 4.5 all-courter. In the past I haven't giving a lot of time to string choice. For about a year now, I have played with Gamma Professional at 59 lbs and have not tried anything new just so I wouldn't have to deal with it. I have always loved natural gut strings but didn't want to cough up the dough for a full set. Since stumbling onto this board, I see that gut hybids are somewhat popular. Any advice as to what I could use with natural gut for a hybrid? I see that several people recommend x-cell, but when I have used x-cell by itself, it seemed a bit too spongy for me. What could I use that would play close to full gut but would add some additonal durability at a lower cost? Sorry, that sounds like I want it all...what combo would play closest to gut? And do most people string with gut as the crosses? Does stringing with gut as the mains offer any better durability than full gut? Sorry for the dissertation. Thanks, James.
