Ha! Did you get the idea for the model before or after you drank

I
prefer the look of the smile cowl and it’s actually quite close to my
design, however I suspect that the “Oh Cowl” would be more
efficient. (I’ve been thinking of modifying mine). I’m willing to
bet that Ed will have some words of wisdom on this subject relating to
efficiency, etc.
Rest
assured though that neither choice will put you in danger of challenging for
the all-time BUC title J!
