I don't know about consensus. Actually, I don't have much use for the term in technology or politics. I look for what works for me, and don't really care much who does or does not agree with me. I use 15⁰. In some cases I have made it a compound angle, with front pins leaning forward as much as 15⁰, as well as 15⁰ to the side, the back pins leaning to the back 15⁰ as well as 15⁰ to the side. The front to back leaning seems to be fairly inconsequential, but 15⁰ to the side works for me. Frank Emerson
