I agree with the notion to hunt somewhere else.I think you would have more success in Idaho or Colorado on one of there OTC rifle hunts, I am betting the dates would be similar. Do you have to hunt in Utah? The extra couple hours drive would be worthwhile I think. I love the Uintas and hunt there about every year, but it's because I live here and it's the only place I can hunt bulls each year.
I do the horse pack in thing and have figured some stuff out and I am not even going to tell you what side of the range I hunt--it took too many years to figure stuff out. Every year I usually have a chance at a legal elk, I passed on spikes the last 2 years and almost had a rag horn this year but it wasn't in the cards. I am not successful every year and I don't have a large hunting party like you will which would make it more difficult in my opinion.
Being that you are out of state can you scout at all? Have you ever hunted with horses before? They are a huge hassle and it definitely has a learning curve to it--I have the scares to prove it! If you are paying a horse outfitter then I would take that money and apply right now for the Wyoming Special general hunt as its a much better hunt than the Uintas. Utah OTC Uintas is not a destination hunt for a reason, unless you have private land or some mega honey hole you would be better off someplace else, even for a hard chargin Marine.
If you want cred pics shoot me a PM with your email, I'm not posting any. Trust me on this one--with that many grunts you would be better off somewhere else.
Not saying that it cannot be done in the Uinta's, but your odds of getting an elk somewhere else is higher. Utah does not even measure the success rates of these hunts and that should be a red flag.
Idaho or Colorado or Montana should be a lot better for general tag purposes. Wyoming has a high success rate general elk tag, but it will take a bit of time to draw in the regular draw.
