For me it certainly has......
I have used up to 29" frames and I found them to help my serve and I adjusted to the length at the net with no problem. The higher swing weight is just that weight. Since I started playing with 13 ounce standard frames, I don't find 340 SW to be a problem. I currently use 27.5, as that is what is available and the SW is still under 320
