The Arrowbatic.
One I'd hate to see:
1) Anything by Togo
2) Anything else by Togo
3) Anything by Premier [see above]
I don't know, I'd be interested in a decent Arrow mouse - either the Mad or the Arrowbatic. Even the carnival ride Hi-Miler.
My dream though, is a CCI mobius-dueler. [I think Mr Althoff can explain this one best, but it's essentially a duel-tracked coaster that doesn't so much race as it runs at the other side multiple times, but ends up at the opposite station.
