I like the idea of braces at a sharper angle . The Dutch barns around my area almost exclusively frame their anchorbeam braces at what I would guess is like a 14/12 or even 16/12 pitch, they all have faired extremely well. It seems that perhaps anything from 8/12 to 16/12 would perform mostly equal with 12/12 being the most balanced , but I am just speculating as I am no engineer as well. tb
