My son is hot to trot to try Prince BeastXP strings. I really don't want him to go full poly, so I bought a pack of BeastXP 17 and Babolat N.vy 16 to hybrid with. Should we string the mains (Beast) the same tension as the crosses? (If it were up to me, he'd be using Wilson Sensation and be happy, but man oh man do those things move around in EXO3 racquets.) Any help is appreciated.
