I sympathize, Ebrown. My work of yore involved developing solutions too. Sometimes a solution just popped up immediately, but we still toyed with other methods, having learned over the years to think designs out. The fifth 'what if' might turn out to be the best.
On the mental lapse, just this morning in a phone conversation with a friend about my lemon of a house, I mentioned the flaws with the piping, its being brittle, and grasped for the word 'hose bib'. Blank... blank.. blank. And, how many times in my life have a specified hose bibs? Hundreds. Ugh. Only I noticed the lapse, but geez.
Good luck on the search.
