OP, a gun best, but most folks don't have that option. I have no experience with Busse or kin. I have been seeing a lot of Basic 11s, and they look awfully nice. I have an ESEE Junglas and love it. At about 22.5 oz., it's not too heavy. Another awesome large blade is the CS Gurkha. I picked on up (black blade/sk5) for $90 locally on Craigslist. It is close to the Junglas in size and weight, and seem like it would make a great chopper and defensive blade. The Junglas and CS Gurkha both have incredible sheaths. I think either would be a great outdoors knife for you and both are good large knife/choppers. I carry a rattan cane bought years ago from CS while in the wilds. It would make a formidable weapon with it's steel ferule. I also worry about animal attacks when in areas inhabited by large critters, but don't forget that our fellow man is likely what you will need protection from. And I personally wouldn't trust pepper spray for bears. I've been hit with it several times (full and direct facial) and while it is very unpleasant, it even fails to work on many people. And people are total wussies compared to critters large AND small. Good luck.
