Hi . Im an agressive baseliner and i love to hit flat and dictate from the baseline . Im currently debating on the Head Youtek Ig Instinct and the Head Youtek Extreme MP . I want a lighter racquet & im debating between these two . Which racquet would give more power but also feel ? Also what strings should i use ? A co-poly like the babolat hurrcane 16 ? or a multi like the head fxp tour 16 ? Thanks .
