Have a Fear of Heights?

[CoasterMatt]

Goliath at SFMM is actually 30 ft taller than Xcelerator, and although Kingda Ka is taller than Xcelerator, Xcelerator's initial acceleration (from 0-82mph) is actually quicker - just about 2 seconds.
Kingda Ka has a really nasty "shake" to the trains as you roll down the launch track, and it's really just a big climb over a tower, an airtime hill, then brakes.
Xcelerator launches, goes over the tower, then does two overbanked curves before braking. Xcelerator is the prototype Intamin Rocket coaster - it's initial test run clocked in over 114mph (the first run on this video).

I seriously love Xcelerator (So far, I think Xcelerator is the nonDisney coaster I've ridden with the most LoTters - I lost track of how many times Chernabog and I rode it).
