I currently have it strung with babolat rmp blast as i have had all my rackets strung with over the last year. I have a pretty poor knowledge of strings, i'vd had red code, hurricane (blue/yellow) and the rpm. I am thinking of using a hybrid between a poly/co-poly and natural gut. Interested in all your feedback. Btw I like the rpm blast very much but i know there are better strings and hybrids out there. I am looking for spin and control. Thanks!
