Whew, read this whole thread over a couple weeks time. I tried a couple ELT setups, and had odd vibration on a number of them which hurts my elbow. This must be the resonance issue mentioned above where the strings vibrate at the same frequency as the racquet amplifying the vibration. The takeaway is to find a setup that works for your racquet and your string combo. I'm now using BHB7-17 on the mains at 32 lbs and Prince Premier Power 17 on the crosses at 48lbs. This is the right combo for my Blade 98 16*19 weighted up to 12.5 oz, and 8pts HL. Hit with the ball machine last night to really test the control of this setup in a controlled environment with consistent ball feeds. The control is fine, although if you 'mishit' a shot too flat (without topspin), right in the sweetspot it's going to go long. Directionally (left and right) I had no control issues.
