I am curious to find out what determines the playability of a strung racquet. Is it the mains or the crosses? I use to thing it was the mains but now I'm wondering if it's not the crosses. The reason I am thinking its the crosses is because they are shorter in length and therefore will not stretch as much as the mains at impact. I'm thinking the amount of deflection of the string bed is governed by the crosses and not the mains. Is this true? I started to get curious about this when I started experimenting with hybrids (guts + synthetics). I never really thought about what the effect of the crosses vs mains before. Can someone educate me. Thanks for the help.
