Yeah, West Edmonton Mindbender, Thriller, and Olympia Looping all have shoulder bars on them. For 2001, Thriller (now Taz's Texas Tornado) gets ugly new shoulder bars and the worst steel coaster seat mold I have ever seen. On the bright side, the shoulder bar mechanism is more conventional than that now used.
The remaining Doppel Looping and Silber Pfiel and other smaller looping coasters...most of those (all?) still have lap bars. In fact, Dorney Park apparently put two new trains on their Doppel Looping a couple of years ago, and stayed with the lap bars!
Magic Mountain's Revolution also has shoulder bars on it, but I presume you knew that already. :)
