My brain now hurts..... not sure if it's the complicated dialog or the margaritas I'm drinking lol! I have found that if a merlin is reluctant to ring up with said quarry then teaching it to wait on is the answer. I have had a nice jack reluctant to ring up said quarry from the fist. I backed up a bit and over the course of 5 day had him waiting around d 500 feet. When said quarry was flushed he completely dominated them at this point. His throw ups were epic and the quarry lost its mind due to his complete dominance of the flight. I will be trying this again with a couple of new jacks this next season. It's natural for merlins to ring however they know when they are out matched physically. The advantage of height from a waiting on post on gives them all the confidence they need to ring up and dominant their quarry.
