Twelve years ago I had closed mouth good curs like yourself; my hunting partners thought the same ways yours do to (against open mouth dogs). Ten years I introduced a plott hound to my pack in order to find colder tracks. I never looked back and today I have all plotts and one cur and I found some new hunting partners. For me, getting the "right" hound was the best thing that happened to me. If you are thinking the hounds may open your curs I would say not likely. If anything, a hound may push your cur dogs and make them better.
I'm in the same boat as you and I agree w you 100% only difference is I'm still in the transition period but almost there lol
