Well I ALMOST had it the other day via a different mechanism, or at least I had the idea via a different mechanism. Very clever, and I had ALOE and AMS down originally and did NOT say to myself (stupid Tom) "hey that could be either!" . Clever idea, and very hard to see even when you see it (as I just made reference to). I'll go back now and find the rest, I only had three of them but it was almost intuitive what it would be once I had PEF and SQA.
