My choice is Possessed (when it was at Geauga Lake), because it popped my launch cherry. Full disclosure, I am sorely lacking as far as having very few launched coasters under my belt. I'm not a fan of heights and I definitely had second thoughts about being in the last row in the seconds before the launch, and for good reason apparently. While not comfortable or pleasant in the slightest way, the lurching brake before Possessed's final descent scared the shit outta me. My only other launch was TTD it's opening season. I honestly felt the 2 hour wait was well worth it, but I found the only thrilling parts to be the initial massive acceleration and the anxiety-ridden wait beforehand.
