Carlyle,
I'm partial, so my opinion my not mean a lot here. Without doubt one of the most knowledgable is a certain Golf Architect who has to remain nameless to protect his identity, but he does post here under initials.
The other is Tony Ristola, whose work I have seen in pictures, and looks to be pretty outstanding. In fact, I will go so far to say that if it weren't for the fact that he can readily seem to get work in Europe, he would be a star over here. At least on this board.
