Hi guys, I'm looking for a new racquet for my son and have become very confused by the various racquet reviews out there. So, I'm interested in all your suggestions. Primarily I'm looking at Wilsons as I can get a good deal through his coach. Physically: He's still pre-pubescent 5'1", 100lb, small hands(4-41/8" grip),wiry athletic build,strong in legs with no upper body strength. Game style: Advanced junior - aggressive all courter. His strokes are reasonably compact(not loose) Good flat serve, developing kicker. Double handed backhand. As you can imagine hard struck ground strokes challenge him at the net (struggles to maintain grip?) Current Racquet: Fischer GDS Rally 102sq" Head 10.5oz Stiffness rating 63 16X19 String Pattern String: Gamma ZO Power strung at 57lb Why change? It is likely that he will grow significantly over the next 18 months as I'm a solid 6ft and his brother is a 6ft 2" 16 yr old. His current tweener racquet has served him well for the past 2 yrs, however his improvement and general playing style warrants a move toward a players racquet. I intend to have him demo a couple but need to short list as there is probably 6-8 ncodes that may be a consideration. My concerns: String Pattern ? I've read many pro's and cons for open and dense string patterns. Will this be a major factor in racquet selection ? Head size ? I think a move to a smaller head size will suit his playing style and from a player development consideration allow him to generate more racquet head speed on serve and groundstroke. Talking to a friend who's son is slightly older, he mentioned his son struggled with the smaller sweet spot when he changed to a racquet with a smaller head size ? Stiffness ? My understanding is that stiffer racquets are more powerful. That said I believe a less stiff and/or slightly heavier racquet may suit given his relatively weak wrist strength and therefore inability to control volleys against firmly struck groundstrokes. Grip Size: At the moment he is between 4-41/8" so he uses a 41/8" with no normal grip, just an overgrip. Some of the ncodes start at 4 1/4" grip size can they be customized effectively ? My 5 top picks so far: nblade, nPS 95, ntour, Nsixone 95, nPro All of these are quite different types however I can see many positives and some negatives for all. Your top two picks with a suitable string suggestion ?????
