The RMD is imho a well designed, highly ergonomic tool made of superior materials with an excellent f&f, so if you are going to get a larger blade anyway, get the RMD now while it's available at a good price. The RMD is an excellent "all-around" blade, with enough heft for light chopping, enough length for batonning thick wood, thick enough for digging and prying but still thin enough to slice (when sharpened to a thin angle) and not bind overly much when splitting materials. It is quite durable, has great edge retention, and is lighter than many "heavy duty" knives while still more than capable of handling the same tasks. Again, the handle is highly ergonomic - many users report that it seems to just fit their hand like it was meant to be there - and the choil allows for choking up to do finer tasks, like dressing that hare. It has a narrow point for stabbing and drilling... I could go on, but I'll stop there.
The RS is an excellent, and again highly ergonomic design, same level of durability and f&f, in a much smaller package (indeed not much bigger than the Warden), the perfect size for hunting white-tail (if you have a hatchet or saw for splitting that pelvis, although maybe you could baton through it with the RS, haven't tried that). The RS, for me, is a perfect general hunting/utility fixed-blade, definitely ideal for processing smaller game as well as just whittling and carving, slicing materials as needed, etc. - the same uses you might put a folder of similar size to.
Bottom-line, however, is that the RS is not a general camp/"survival" knife. I'd pair this knife with a larger blade or a hatchet&saw for the big stuff if going out in the woods with that in mind. I'd be (and am) perfectly comfortable taking the RMD solo (a saw might be nice but isn't all that necessary) - the RMD can handle the tasks of the hatchet (paired with a baton) as well as the tasks of the RS (though a bit more bulky than might be ideal). Key point however - be sure to reprofile the edge of either knife to an angle that suits your needs, the Swamp tends to leave them somewhat obtuse to handle more extreme beatings so if you want a thinner slicing edge it'll require tending to.
Alright, that's my $0.02 BOTH great knives, each with a specific niche. Good luck!
