hi everyone, just something that made me curious...i looked at a racket strung by a local stringer and the racket seemed to be skinnier and longer. Would this be because i haven't tightened the 12 oclock and 6 oclock holders on my stringing machine as a local stringer. I'm pretty new to stringing...am i supposed to tighten the 12 oclock or 6 oclock racket holders or just leave it in the racket's natural form while stringing? if i do have to stretch the racket before stringing...how much should i stretch it by? Sorry if i'm a noob stringer but i'm having to learn all on my own and from the forum here...which has been great so far...but i couldn't find much info on this topic.

THANKS FOR ANY ADVICE IN ADVANCE!!
