I've done a bunch of solo backpack hunts...heres my take;
Do it! You will learn one heck of a lot about yourself from one week solo in the wilderness.
Focus on reading the country rather than just hiking with a bow. It sounds hokey...but the more you become one with nature and understand what its telling you...the more effective you will be as a hunter. Make 'Trying to figure them out' the fun part.
You will have to cover a lot of ground usually to get into them...90% of country holds little...keep going. Then you can slow way down and hunt the 10% of country they are in.
Important to be mobile...go as light as you can. Most first time guys tend to bring too much clothing.
Keeping a positive attitude is more important than your gear....but good gear is the icing on the cake!
As you already know, you'll get a lot of opinions here on everything. It sounds like you have done your research and keep on keeping on about that. As Beendare says, DO IT! Man, life is short (a fellow coworker of ours was killed at work yesterday) and you just never know.
Now, i'll be brutally honest as I am getting more and more selfish about Idaho. I'd just as soon not see any more hunters come! But it is a really good state to backpack hunt in both for deer and elk and you'll find a good place to go with the proper research and questions.
Good luck!
