I want to put on Luxilon Big Banger ALU Power Fluoro either as a hybrid or full set. If I do it as a hybrid with the poly in the mains, do I want the tension to be a couple lbs less than multifilament crosses? I'm confused b/c with normal synthetic, you would string the mains a couple lbs higher. I currently string my racquet at 54 lbs crosses and mains with a full set of Prince Synthetic Original. Is it bad for the frame to have the mains strung at lower tension than the crosses? Thanks for the help.
