Typhoon I picked up the v2 from Kelly a while back. When I ordered it, I had it built with the longest shaft listed, and I got the weight kit. That way I can play with the weights. After that, I think it's a learning period. I need to work on my alignment when I'm putting. I'm either way off, or dead on. Speed is pretty good when I'm off on alignment, and a little high when I'm dead on.
While the putter isn't glamorous, I've found one I want to keep in the bag for a long time.
That said, the lab putters definitely have a following and I think for good reason.
I think you are right when you said that everyone releasing their own version is proof that the science is there.
