If you are looking for "backcountry" what i see on Beaver traps website about their hunts doesnt really equal that. They use wall tents with generators and ATV's and Pick-ups for hunting. If that is fine for your group then no worries, but when i hear backcountry i usually think of a string of horses and mules. All depends on what you are looking for though. . As a guide I can tell you if i ever make enough to be a client instead what my line of questions for an outfitter would be from my experiences....
1. Success/Opportunity rate 2. Quality of bulls (example of all their hunters last year how many bulls went over 300) 3. How long have their guides been with the outfit (if you have an outfitter who doesnt have a single guide of long standing...there is usually a reason behind that). 4. Number of hunters in camp each hunt if booked full 5. Amount of pressure from other hunters in the area.
I guess those would be my most thought about questions to narrow down an outfitter. The outfit I work for doesnt have a single guide with less than 4 years for them, and that is me. The other 3 guides have been there 10-20 years respectively. For my hunting area, we are a backcountry outfitter whose camp is 18 miles from the trailhead via pack strings. We dont have to worry about the point system much because we are in a general tag area so many of our hunters can hunt with us every year if they put in for the special draw, or can easily get lucky and draw with 0 points in the general draw. That being said, for an area you are looking to hunt this question probably will not be as relevant, But the amount of Return clients an outfitter draws in really shows what kind of outfitter they are. We bring in roughly 85% return hunters every year if not more. Our first 3 hunts are usually booked with returns. Its a good thing and shows prospective hunters confidence in booking.
Years ago I worked for an outfit in Idaho for 2 years that had nearly all new clients each year..there was a reason. Hunting was tough, bulls werent big and the outfitter made a lot of big claims in his phone calls that a client could have noticed was false just be adhering to some of the above questions. I left that outfitter mainly for the reason of not being able to stand new people every year with false expectations. There are definitely great outfitters, and bad ones. Using some of those questions can hopefully help you get a good idea of the outfitter. I personally believe the amount of years their guides have been with them truly shows a lot about the outfitter. If you have any other questions Id be happy to try and help or answer. I do not know much about outfitters in those areas otherwise I would give you a reference if I had a good one. Good Luck.
