I love that combo as well! I feel the same way about the PM2, I remember it being available but for whatever reason decided not to put it in my cart! I'm not as big of a fan of the Para 3...but got one preordered so I can have the combo in a more pocket friendly knife than the Millie.
The Millie is weird to me. It's big, but it's not! It's long, but thinner than the Shaman's that we love. I like that there seems to be like 3-4 comfortable grips I can use as well on that big handle. It's very light weight as well. I'm sure it's better to carry in the back pocket, but I've always got my wallet and a notepad in my back pockets so I carry it in my front pocket. Not a terrible fit, but tough to get my phone out if sharing the same pocket.
I'd say if you find one for a good price, or a combination you desire, give it a try! Seems like another good outdoor knife for when you're at your cabin, maybe it would be the one to get your husband interested!
