I have playes with the 21 gauge 0.70 mm Micropower string from Ashaway for the past few years now. I initially loved this string because of the surface texture of it. Very rough, indeed. Now, however, as I have been continually increasing the tension of my strings I have started to become slightly disappointed in the Ashaway string. What do you guys think about the Micropower? I am considering shifting to, perhaps, a bg-66. Any thought on that? What my fellow national training team members tell me is that this is probably the best string for the offensive hardhitter.
