I was just going to post something about this, good timing.
I've got a set of Shooter's Ridge (i think) breakdown for ease of packing. They're nice in a pinch, light, but can be difficult if you're not used to them.
So, I've been considering something different for the wife. Been looking pretty hard at the Primos trigger stick. The bipod option crossed my mind, but I just think over a long day it'd be too heavy for her. The Primos is heavy, but at least I could carry it for her, and I wouldn't mind packing them around while hunting coyotes.
All I can find them around here for is $100. Not sure if I want to drop that kind of dough.
