I've been hitting with a few capped TGT 307.2 for a couple of years, and decided to buy an Ultra Tour, because why not owning an H19.
First, I was concerned with grip size, because I replace the synthetic grip with a leather 0.5mm calfskin grip, and some Wilson frames have felt too thick in the past. Fortunately, the grip size is pretty comparable to Head pallets.
I also added lead on the whole area covered by the bumper, bilaterally, of course (around 6 grams). The stick came in at 308 grams, and it's now sitting at 345 with the leather grip, strung with 1.25mm, with a Tourna Tac, and a Sampras dampener. Forgot to run it through the balance beam. I was basically playing it by feel, and these mods felt perfect.
Power is more than sufficient with alu power spin at 50 lbs, and, as other have stated, spin is better than, for example, the blade 18x20. I do get more power, "pop", and spin with my pro stock radicals, but they only feel good with a couple of strings, one of them Cyclone and the other, Solinco Revolution.
With the Ultra, I enjoyed being able to rip my groundstrokes and drive through the ball without being too concerned about over-hitting. Hitting that sweet spot feels great, and it isn't really much smaller than my 307.2. Very approachable racquet to hit with. The only issue I can think of is in terms of power with people stringing it too high, and players used to more loopy trajectories. This racquet plays pretty similar to my pro stocks, just more comfortable, and some 20%(?) less power, which is OK.
I did break my first string job after 2 hours of play, which is rare (damn alu spin). I got it restrung with Cyclone 1.25mm and it felt pretty similar. I've played with it for around 7 hours, and I'm learning to really appreciate the feel and freedom to swing hard. Now I need to get my serve a little more dialed, and I think I might switch to this one.
My .02. Thanks everybody for all the info you've provided. I'll post a few photos soon if anybody is interested. I'm a Norcal 4.5 and was lucky enough to beat my 5.0 buddy playing with this stick for the very first time. Maybe I was just excited about the racquet. It did suck to break strings soon and pause the match for a 30 minute restringing break.
