5 Star has been out a while - much longer than ALU spin. Looking at the RSI Poly chart, it is very stiff and thick, both of which I favor. I also like textured string - ALU Rough is my regular string. So I'm thinking, 5 Star could have a lot of potential for me. Anyone out there (who likes Luxilon and other stiffer polys already) have any experience with Lux 5 Star? Thanks!
