I usually play with msv focus hex 17L mains 53# and prince lightning Xx spin cross's 57#. I just strung msv mains 53# & Babolat Nvy 57#. The feel is much better than with the lxx especially on volleys but my serve is suffering with a lot more double faults and I am more unsure of myself. Should I adjust the tension to give me more spin? Any recommendation on what I should do will be greatly apreceated. Also if a soft more spin friendly cross recomendation is available let me know. Ultimately I want the feel of the nvy & the spin of the lightning. Thanks!
