I'm glad to hear the short shanks work just as well as the long ones. My only experience so far with metal faucets is with this contraption:
The shanks stick out the back of the vertical plate and are just out in the air. It's important in that application that the shanks be long enough to have an icepack resting on them to keep them cold. Otherwise the faucets and shanks get warm and pour foamy beer.
I also plan to put the shanks over the hump where kegs don't fit. It's important that the shanks don't block even that area, though. That's where we store the lobsters as we catch them, then get them back out at supper (or breakfast or lunch) time. As the beer supply goes down, the lobster supply goes up and keeps the universe in balance.
