New England Rope's Fly and Yale Poison Ivy are static kermantle arborist ropes that are supple enough to hold a Blake's hitch and according to manufacturers de_script_ion have minimal but sufficient stretch to absorb shock during a fall. When you climbed with me you descended on my Poison Ivy so you have an idea of what that rope is like. The Fly is very slightly less diameter.
So if you want a rope that will serve well for SRT and DdRT either of these will do the job. A traditional static kermantle is absolutely useless for tying a Blake's Hitch or any friction knot.
You could by a 30 ft. piece of Fly to meet your camping requirements. Wesspur has it for .67 cents per ft.:
