I don't know that I follow all of what you are describing, but it sounds like you are keeping your bent right wrist and getting to an auto snap release, pitch elbow. The only reason I would guess you are giving up some distance is by focusing on the bent right wrist, your release isn't as free as it might otherwise be.

Try a focus on aiming point with your driver, it may free things up a bit and get much more distance.
