I have to agree with you guys here, Manhattan Express was by far the roughest ride I have ever been on. You can stand next to it and hear it jumping around. It makes SOB seem like a B&M... For and idea of how bad this ride is, go to this link and scroll about half-way down the page to the Manhattan Express video:

I'm sure some of you have seen this movie, but I love it. Mostly because it was exactly how I felt on it a few years ago.
Speed is an all around awesome ride. Getting launched out of the station and on to "the strip" is a feeling like no other... It also comes very close to the things around it.
At the Stratosphere, I didn't waste by time on High Roller, but Big Shot is also an amazing ride. This may be blasphemy around here, but Big Shots perch 1,000 feet in the air easily gives this ride a win over Power Tower. You get shot up. and you cant see the tower below you... its breathtaking.
Unfortunately, I didn't get on Canyon Blaster or Desperado...
