I know that you advocate a homebrew of 132 combined with LC, but I seem to recall that someone (you?) also suggested a ratio for a mixture of 132 and 131. I've searched the forums and haven't come up with it, so either I'm dreaming, or I'm lousy at conducting searches! Regardless, what would you suggest as a good ratio of 132 to 131 for adding to a 4-quart system?
