I use the eberlestock X1A1
no special bow bucket to add on, built right into the pack

I've been using it predator hunting, I put a rifle in the built in scabbard and hop on my snowmobile and ride miles in 3-4 foot of untracked snow cutting tracks.
works awesome on the snowmobile that way. I haven't carried the bow much in it but I know it fits well in there and doesn't wiggle around testing it.
I got a jack in the box, and CS24B foxpro stuffed in it right now - still plenty of room for lunch and winter survival stuff too
