hi all! i have been playing with alu power rough now for a while and love the string, great power and great spin BUT the string dies WAY too fast. i play 5 times a week for 2-3 hour per session and cut the strings out after 4-5 hours. they are great fresh and horrible when used... what can anyone recomend to replace them? criteria: good power spin enhancement would like to start using a black string (i know it's cliche but i do like the look) string that plays well for more than 3 hours!! i have tried RPM blast and wasn't overly impressed; also tried blackcode and again wasn't overly impressed. let me know what you think - please!!
