According to reports on rec.roller-coaster, it had something to do with excessive violence going through the trim brakes. Having ridden BGW's Mouse and Hersheypark's Mouse, I can believe this. I'll bet Disney hasn't been running their Mouse the way Hersheypark runs theirs...so they have to contend with violent braking.
