One of my teammates still throws one of these. He's a medium speed, medium rev guy with a pretty high track. He has a basic label drill on it, and he gets a really smooth arc reaction out of it. It doesn't give him a lot of room. Miss outside and it won't recover, miss inside and it sits on the nose. However, when he gets lined up the carry is typically pretty good.
My guess is that it will likely overlap with your Purple Monster, but if it's free, why not give it a try.
