To the experts in the forum; I always break the crosses, even with a full bed of multi. When I do hybrid, my stringer always recommends to put the poly on the mains and the multi on the crosses. What happens if I do the opposite (poly on the crosses and multi on the mains)? Would my strings last longer given that I usually brake the crosses? Am I going to have the same effect on hitting the ball? I was reading that Federer uses that setting. Thanks for your input.
