The more I hear about Vijay the more I'm skeptical about him. I was already on the fence but the way he handled the whole Deer Spray thing really turned me away.
If you sort of liked the feel of a Scotty, but it's just not right then try a Ping Anser putter. Also I know you said you want a blade putter, but the new Golo 5 line is worth a try.
I make sure to keep my hands slightly ahead of the ball at address and to have a more compact swing. Also make sure your not playing the ball too far forward in your stance.
Yeah I met Fowler at the RBC and was very impressed with him, talked for a few minutes before he excused himself to go sign for some waiting kids. As for most disliked, probably Bradley for many reasons listed above.
