Is there any advantage to varying tension between mains and corsses in a setup that is purebred not hybrid. I'm going to switch from my alu rough/vs touch to full alu because the gut usually lasts me a week lol but any way I use a 90 sq. inch racket and i think 54-56 (still undecided) lb for a full alu rough sounds like a nice starting point but should I retain the seperate tension I had for mains vs. crosses that I used in my previous setup? What exactly does this do? I did realize that it added various effects vs the same tension for both mains and crosses the most notable being the increase of sweet spot size, but this was done wiht my hybrid setup. Would it make sense to do a similar thing with a full alu rough, and if so what would you guys suggest as the tensions if I would use about 55/55 tension normally.
