Ideally I would want something big, the 911 or even the 1311, but probably the 911 for slight weight reduction and ease of carry. I would also want something a bit smaller Either my Bullnose Regulator or the S5/Wardog. AND I would also I figure carry the Swamp Warden with bpiatt scales.
You CAN get be with only one knife, two are better and three are best in my opinion.
