I noticed that from the pictures. The Tour 100s seem to have the same roundish shape (and I'm assuming weight distribution) as my Warrior 100, while the 98's are more oval-ish. I added weight at 12 to my Warrior to shift some hoop weight towards the tip and I like that better, so I'm guessing that will be similar to the 98's stock set-up. We'll see.
It might alter the weight distribution, but it won't change the shape, which ime, seems to have a negative impact on my net play. The strange thing is that I feel confident playing with it at net, but the results are not so good ...
As to the Tour Pro 100 ESP, I'm hesitant. The only reason I'm trying the 98 ESP is because the regular Tour 98 gets such an awful review and the 98 ESP's review makes it seem like it'll be perfect for my game. Ordinarily I wouldn't try an ESP pattern for fear of loss of control and the ability to hit anything remotely flat.
I haven't played the tour 98 esp stock (since mine are customized), after trying the warrior 100 ESP (which I sold), and now playing with the tour pro 100 ESP, I can tell you this: the ESP tech / extremely open pattern is altogether a different beast than your reg 16x19, 18x20 racket.
I customized the tour 98 esps to rebel 95 specs, in hope of creating a perfect ESP Rebel 95 hybrid, but it doesn't work that way. Yes, I did manage to get an ESP racket with high weigh and SW, but those specs do not manifest themselves as they do in the more trad tight(er) pattern.
In my experience, the ESP racket work best at lower SWs, where you hit full swings aggressively (going for it). This makes them play the opposite of how I normally play a Prestige IG Pro f.inst.
String choice and tension also plays a big part here. These rackets are made for thicker gauges, and there is little consensus on tension. Some like full poly at 60lbs and above, some like low 50s / high 40s. In my stock TP100E I have 15 g Volkl V-star @58 lbs, and that feels very, very plush and soft. If I went with the same string, I'd prob. go 60-62 lbs next time. In comparison, I use Volkl Cyclone / Cyclone tour 18g at 50-52 lbs in my Prestiges and Rebel 95s.
Btw. I sold the Warrior 100 ESP I had for a short while as they were way too powerful and erratic. Those were strung with prince beast xp 16 @ 60 lbs. Leading up that racket would not result in anything positive without a thicker gauge string with even higher tension to regain control.
