1. Tower of Terror (WDW) - Best drop/dark ride in the world hands down. Different ride every time plus great atmosphere and a perfect theme to boot
2. Drop Zone (KD) - When its running, its really good. Dropping from that height and not hitting the brakes till the bottom is a great feeling. I just wish the newer Intamin drop towers weren't as controlled so you'd have an incredible drop like this.
3. Angry Birds Detonator (Thorpe Park) - Who knew a ride themed to Angry Birds would be that much fun.
4. Mega Drop (state fair) - Probably one of the more intense drop towers I've been on, you pull some pretty good G's on it.
5. Voodoo Drop (SFA) - I dunno why Carowinds' drop tower is so forgettable because this one is really fun. Its about as forceful as the state fair model but at half the height
6. Doctor Doom (IOA) - If you leave your restraint high enough, you get a really good amount of ejector on this thing. I often skip it but every time I reride, I remember why I like this thing a lot.
7. Wild Surge (BGT) - My favorite drop tower in Tampa. It gets overlooked by Falcon's Fury but definitely don't overlook this gem. Its fun, has a long cycle and you get some good air on it.
8. Screamer (Fun Spot) - Both Screamer towers are pretty much Wild Surge but with less theming and not as good of a ride cycle.
9. Falcon's Fury (BGT) - The whole facing down gimmick is really intimidating, but the drop is super weak, plus it goes down all the time
10. Mach Tower (BGW) - I actually really like the drop on this, plus the view and the rotating seats really add to the experience. My main issue is the constant downtime this thing usually gets coupled with the really uncomfortable seats.
