I love the feel of a thumb hole, but hate carrying one for coyote calling. They’re just an awkward shape. Dual side flush cups help, but even still, aren’t as handy as a non-thumbhole design. I almost HAVE to use a high angle pistol grip, so something like a McMillan Game Warden, A3/5, Boyd’s Pro-Varmint, Manners T4A, etc All of the comfort of a thumbhole with slightly less bulk and weight.
