I'm goin on my first ever elk hunt this September. 161 rifle hunt In nevada. just to clarify what your sayin for my education.. Am I correct to assume the rear quarters go in the 2 20"×30" bagsTAG bags are a pretty different material from Caribou or Black Ovis or the Allen backcountry. Kuiu is a little different but still not the same material as TAG. I have bags from all 5 companies and prefer TAG. However TAG does not offer a 20x30 which I find is ideal for hind quarters bone in or out you need that big opening. Meat will stick to all of them but the caribou fabric is a little more coarse and will actually embed the checkerboard pattern in the meat which I think makes it stick worse. I usually carry 1 caribou or Allen 20x30 and 1 kuiu medium quarter basically same size and then 3 TAG bomb bags the bigger size I put a front deboned in each and the neck meat in the other. Then the 2 smaller tag bomb bags one for backstraps and the other for the tenderloins. This is for elk hunting. My hunting partner has the Black Ovis and I have my wife setup with the 4 Allen backcountry bags 1 TAG large bomb and a medium kuiu zip.
