So I feel a little noobish asking this question but I have now seen different set-ups and opinions so I am confused again. I string my mains tighter(usually 2lbs) than my crosses as I was told this would increase the size of the sweet spot. I dont have any experience stringing myself so generally listen to the guy at my local pro shop, but we all know they are far from infallible. Recently I been seeing a majority of the people on these boards string their crosses tighter than their mains, and in thinking about this it made sense to me as the mains would be able to more easily slide across the crosses on impact and snap back into place thus creating more spin. Can one or more of you kind people explain the thinking here, pros, cons, effect etc.
