Great minds do think alike. I checked that tactical pack and it's very impressive. I guess I'm being a bit fussy. I want the pack to hold my box and tom calls, be hydration compatible and be able to carry a tom back out of the field. I usually hike anywhere from 3-8 miles while hunting and don't want to carry a tom over my shoulders for several miles back.
I don't care about a seat as I rarely use them. Having ice water in a hydration badder is like night and day for hiking up and down hills for miles though. Now if Badlands would hurry up with the new turkey vest they're still designing (I use their packs for deer hunting and they're spot on). Until then, maybe I need to find a way to anchor my CamelBak to the back of one of my current turkey vests.
