My biggest gripe with it stems from the fact that the vast majority of tennis players don't need polyester. I have 60 yr. old seniors asking me to string their sledge hammers with full BBO, while wearing tennis elbow support on the same arm that they hand me the string with. This is getting ridiculous. I'm a 19 yr. old D-1 college player that strings on weekends and I have lived the polyester revolution firsthand. At my academy, I was breaking strings every two days at the age of 13, due to my extreme western grip. This was the reason that they taught me to string my own rackets. I stumbled upon Pro hurricane, looking for something to last longer than 2 days. I grew accustomed to the 'dead' feel and I strung the entire frame with the stuff. At the same time that I made the switch to polys, I saw the majority of my peers make the same transition. We all noted an increase in confidence in putting the ball away, as it just seemed to dip into the court at the last second. Reasons why we use polys: 1) We're have no idea what tennis elbow is...sounds like something from Operation (seriously...people are hurting themselves just to try a string they end up hating and didn't need in the first place) 2) We all use Western forehands that generate massive amounts of topspin 3) We're all string breakers (our idea of a durable string lasts a couple of weeks not months) 4) We like the fact that our stringbed feels like a board (wtf is dwell time?!) Polyester was born out of necessity as another option to kevlar. It's far too stiff/harsh for most people. Yes it has changed the game, but only if you have the required racket head speed to take advantage of it. This is just my rant about the current poly fad that the world is going through. I understand that the younger gen isn't the only demographic that is able to take advantage of these strings; it's just the point of view that I have the most experience with. Please feel free to comment on the issue as you please; I'm interested to see what people have to say on the matter.
