Definitely reduces the complexity of the ride, but then means you have to build a ~40ft deep pit to house it, which is expensive and, in many cases, impractical.
The sky swat design just never really worked out; it's just one of those things really. Sure, they could spend a whole lot of money to improve it and create Sky Swat 2.0, but the concept of it just doesn't really work. The rides themselves aren't particularly popular either.
