To be able to say things like 'so-and-so has a good double' is one of those things that can seem appear simple in concept, but is masterful in execution. For instance, the use of elastic rebound to take a shot from the position you start in, without taking an extra step first to set up, is one of those details that can make such a huge difference for how low key it seems.
If you're considering suggestions, i'd like to see your take on the most frequent types of pinfalls in freestyle competition; what guys happen to be the most prolific, what that they'd happen to be doing to make it happen.
