RE: Advantages to a new string
That is my 13 year old (14 now)daughter's go to hell look andplaying around with the camera.
The biggest issue you have with serving not being the same with the twist is a string that will not settle,therefore,a peep that constantly rotates.Which means an inconsistant string.
I don't build string but my guy has discussed this with me and not sure if he ever mentioned the speparation issue being a result but seems plausible to me.
