Customized with lead in the butt, neck, 3, 9 and 12...awesome power, stability and spin. Stringing thus far is a credit card bottomless pit, however. Every string to date has been durability Lux NXT 4gs, RPM Blast, Solinco Tour bite. Each has lasted between one set and two matches. Wilson says ignore what is listed on the racket Lux NXT 4gs and try Alu Power 127 spin. Fingers crossed! Love the stick, not sure I can afford it.
