I usually string my rackets pretty tight so I'd be the wrong person to ask about tension, its really about what you prefer the Prestige isnt SO low powered that you can't string it between 55-58. The low gage offers more pop and spin, and on the tight string bed I think a thinner control oriented poly keeps the control of the prestige but adds monster spin. Hexablade 17l came to mind because its a softer, control oriented spinny string. The weisscannon strings would be great too.
