Believe it or not, I've been using cheap $3-5 synthetics all my life which might be a surprise to many of you. So this jump to $9-12 synthetics like Laserfibre Supreme, Yonex Tour, etc. is a huge one and I'll probably be shocked at the increased performance, it'll probably be like night and day. And to think I strung all these fine Yonex/Wilson/Head rackets with the cheap synthetics all this time, it's probably a crime by the standards of some of the people on this forum. Anyway, I'm really excited about this whole area of stringing and plan on re-stringing most of my rackets with multis. I don't plan on going so far as "proportional stringing" or using hybrids.
