Not going to be much help, but I'm thinking through the same thing right now and leaning toward not applying for Arizona buffalo this year. At $5,400 for a bull tag and $3,250 for a cow tag it is just a little more expensive than I want to spend IF I drew the tag.
The season dates for the bull tags also conflict with other hunts this year for me also so I would need to just go for a point only this year anyway.
Reading up on it a little it sounds like the North Rim herd is tricky to get on the right side of the park line during hunting season and the other herd sounds more like a shoot than a hunt and I could do that a LOT cheaper somewhere else whenever I wanted.
I haven't bought a point this year as they went up to $15 and I'm not sure with the price of the tag if you draw and the other challenges associated with the hunt if I want to even mess with it anymore.
If you want to deal with a hunt where you have to catch them on the wrong side of the boundary line, this year it was 100% draw odds for nonresidents for a Wyoming Cow tag and the tag was a LOT cheaper too. Success rate is lower though.
Right now I'll just keep applying for the Wyoming bull tag along with a few thousand others and hope I hit the lotto.
My 2 cents on the subject.
