Kerik, Great stuff Hoss! I'm impressed how that 3A covers 11x14 so well. Very sharp out to the edge. What size hole is in your stop? I have a 3A but no stops for it ( plus it is a little rough). I think wide open it is f4. You need to get those ambros in the show my man. Build some wooden shipping crates if you need to. These are great stuff and we need to see them exhibited. I'm surprised I missed this one before. Robert
