Got my hands one one so I'll follow up with Rabbits thread. First, and I think this is very key is what the stock weight and balance is with "original" horrible Yonex grip. Weighted 11zz strung with 16 gauge syn and vib. dampener. I hate the Yonex grip they put on - its cheesy and is so THIN its amazing. Anyway, took it off and put a Gamma Hi-Tech grip on, wow, that added like 6-8 grams weight, so now racket weighs 11.3 oz and 7 pts HL - this is just by adding an "average" grip. Next added 2/10 of an oz of lead tape - 2/3 to 3&9, 1.3 to top (a rather small mod actually). So with a very slight mod racket now weighs 11.5 oz and 6 pts HL, very similar to my Pure Storms, so I can compare. Went out to his some serves, felt great for pace/spin/accuracy. I could really take a hard swing on a kicker and have confidence it would go in, and it kicked well. Reminded me of my old 1500 Yonex I used for a few years. I'll play some this weekend and follow up. P.S. for Rabbit - first I would suggest you weigh and balance the demo you have. If you still have them for the weekend I would strongly suggest you do what I did, just replace the Yonex grip with something mormal and weight the head up a bit - not too much like I did. Be interested if there is a big difference.
