Cheers.First I have to admit I am not against having multiple bags. I use the egg for PRS style and matches like ours where it's spread out up and down draws but the entire day <2 miles. It holds enough ammo and snacks. For two days, we just have to remember that we rifle ammo, etc for day two. Even in a lot of field style matches the distance for the day is not often that much. That said, there are some.
By the time I personally go to a hip belt, I want it to be on a light for capacity bag and probably am asking the hip belt to help carry the weight of the rifle on and tripod. So not sure I'd but the egg in a larger version.
I can get the Origional Dragon Egg considerably cheaper so think I'll give it a go, can always buy another bag later on.
