Sticking to the orignal poster's question, I'd happily hunt with either of them. For a non-resident, you're only going to get one of these tags once in your lifetime, and most non-residents will never draw a strip or henries tag. With that in mind, I'd do this hunt with a guide. I do a lot of hunting on my own, but I also do some hunts with guides and either of these hunts would qualify for that type of situation. Once in a lifetime with chance at an incredible buck, the guide doesn't cost that much more than doing it on your own when you consider the overall situation, especially if you have limited time for scouting like me.
Now, unlike a few of you, I don't know either of these gentlemen. Also unlike the majority of you, I've actually spent a little bit of time actually talking with both of them in person, as well as on the phone. I found both to be honorable, friendly and very helpful. I spent a few hours with Ryan at his office in Kanab after my son's 12AE Kaibab hunt (which we did on our own), and spent a little time on two occasions visiting with Doyle when I was hunting Monroe in 2008. In my opinion, they're both fine gentlemen whom I'd enjoy spending time with around a campfire, and would love to spend some time with out looking for a giant buck.
I can go on any number of deer hunts on my own, and do so regularly. Unless lightning somehow strikes, I'll never get to hunt the Henries, but I should be hunting the strip in the somehwat near future as I'm a max points holder among the non-resident pool. For that hunt, I'll probably hire Clay Bundy, as Ryan recommended him highly and he seems to be a very decent, honorable man, in addition to a great mule deer guide. Ryan spoke very highly of him, and everything he said was confirmed in conversations we've had. That said, I'd still love to hunt the strip with Ryan Hatch.
