I do about 15 track days per year in my dual duty F80 M3 with 295/30-18 square tires on 10.5x18. I'm advanced solo.
On Saturday I tried the TAPs at my home track of Lime Rock Park. It was a disappointment. The tires had 5 prior heat cycles at Watkins Glen, including an overnight "cure period" (one session one the first day, then 4 sessions on the second day.)
At WGI the tires were comparable to the RE71RS in terms of pace (similar theoretical ~206.5) and heat tolerance. Saturday at LRP felt like I was driving on heat cycled tires. The first session was meh and the grip got progressively worse. Weather was low 70's and sunny. I tried cool down laps and fiddling with pressures, but nothing helped. Meanwhile, back in steamy August I pounded on the RE71RS all day and was still able to consistently lap sub 60 seconds. See AIM solo snips below. Also, you can see me sliding around in the vid linked below.
The construction of the Hoosiers feel stiffer which provides quicker response/feedback on initial turn-in compared with the RE71RS. They feel good under braking. No squirm (probably due to the shallow tread depth). They don't make a lot noise at the limit.
The RE71RS sidewall roll on my outlaps until tire pressure builds. Not as bad as the AO52 though.
