Finish swivel
 

I'm having a hard time conceptualizing the finish swivel without
losing the flat left wrist. Anybody that can help would be greatly appreciated. The best I have been able to come up with is using Brian Manzella's concept of "wedding ring up." I already have a pretty good hook spin on a lot of shots, so I'm worried this will make it worse. Also, how would you swivel after using vertical hinging? (Seems like it would be useful in the sand).
Happy New Year everybody.
