As a kid who grew up with a dad who helped design rides for Six Flags Big Shot was pretty cool for a quick thrill. It's an extremely fast ride but a good one and it all happens at the top of the Stratosphere. It feels like you're going to fly straight off the top as it accelerates pretty fast then with no pause in between it drops you straight down causing you to come out of your seat a little while getting that good stomach drop feeling that says "Now this is a ride".
In my opinion it's the best of the rides there.
