I am stringing my Head Metallix 4 with Blue Star 17 Mains @ 57 and Gosen OG Sheep Micro 17 @ 57 Crosses. The racquet feels like one big sweet spot. I have gained a whole lot of control but lost some power. I want to stay with the Blue Star but need a little bit more lively feel and a touch of power. What do you thing about NXT Tour 17 crosses?? or Blue Gear @ 59 and Gosen crosses @ 57 ?? Any ideas would be appreciated.
