I threw it at a demo with a typical demo layout, pin over bridge cg in palm. It rolled very smooth for me, I decided to drill mine similar...a touch weaker with the pin over the middle and cg in palm, and it was a little uncontrollable off the end of the pattern. I had to sand it down a bit to get it reading early enough, but it's much better now. Still, I wish I had put a stronger or earlier rolling layout on it. I'd say go with your favorite benchmark/control layout and you won't be disappointed.
