Is 23lbs too much for my racket? 1----- If I wanna have 23 lbs approx. tension for my racket(Iso Power 200), what would the main and cross tension be? 2------And I did browse the past threads but howcome not many people mentioned about Iso Power 200? is it becasue this model is too old? 3------I am from Asia(Taiwan) and I weight about 69kg, ,170cm height so I'd like to know if 2U G4 is suitable for the size like me or maybe go for something else? 4------If I wanna replace my racket but based on the feel of the Iso 2oo, with higher bughet this time what can you suggest? For reference: I hit quite hard for certain strokes and I'm strong with arm power, so heavy head rackets might be ok for me. Also my hand is average Easten size. Any one with any comment, just put it down, anything at all !
