RE: Outfitter vs No Outfitter
An outfitter, the right outfitter, will have access to land with a limited amount of hunters. The success ratio on public land is much lower and you almost have to be an outfitter yourself with all the gear you need. I am always for DIY public lands hunts, but I am also willing to have a unsuccessful season if I do not see what I am looking for.
For your needsfrom what you stated I would go with a well researched outfitter. SRM out!
