I have been playing eith alu rough for a while but it dies so damn fast habe decieded to change string. Have play tested loads of strings i have come down to my two favorites which are RPM Blast and Technifibre blackcode. I find that i can get more power from RPM BLAST and it makes a great poping sound on shots but i am worried of reports it dies quickly. I dO also like blackcode although my preference is rpm but i gather the tension matainence is better which is important for me. Let me point out i use an aero pro drive strung at 45lbs.... What do people think of the two strings, whats the string life overtime?? I have hit with both strings for about 6 hours each and so far both are doing well. I hit with loads of spin and big groundies... Tell me what you think of the two strings, want to buy a reel of one as i have alot of matches coming up and need to get strings sorted asap! Thanks!!
