I just strung my racket using Reaction as the cross and ALU rough as the main, and I can't really say that I like it enough to make it my new string. I previously strung NXT Max and changed to try something new and cheaper. But the Reaction seems to make less pop, less spin, and a bit stiffer than the NXT. Kind of feels dead after the first few hours? Anyone feel the same about Wilson's Reaction? Any recommendations for a cross string that plays and feels like NXT?
