A gym mate of mine was showing me some cool transitions last night, since he saw that I was working the twister roll. One of the strongest ones was a wrestler's switch to a spladle (kind of like a banana split) off of a low single leg. The inside hooking leg is the same dynamic as the twister roll, the transition is looser due to the lack of a grapevine, but it works smoothly as a transition to the back or the truck instead of the spladle.
Just for fun, a picture of a spladle..
