its difficult to maintain an Un-cocked right wrist but really brainless to maintain a level right wrist

Nuke -

I could be half-cocked or a bit brainless myself...but I think the grape goat is referring to his right wrist position as it nears the top/end of the backstroke. Maybe some clarification from Grapegoat would help.
Double cocked.

The Key does a good job of keeping the right wrist from cocking. It has a strap goes across the base of the fingers that secures the top portion. The internal metal piece is bendable and has a slight curve around the base of the index finger. You have to really force a right wrist cock.

You can also use it on the left hand by bending the metal flat. Keeps the left wrist flat.
It's not ideal, but gets the job done.
