I'd take one with the exact blade shape of the one you posted. Res C would definitely be a plus. I would not want one if it was thick and heavy though. That is one of the great things about a khukuri - the blade shape does a lot of the work so it does not need to be a beast to perform. I do not work out of my truck and often have to carry stuff when I'm in the field, so I prefer the least amount of mass that will still get the job done.

fwiw, I always thought that SY was the best choice for a good value in a working knife! So good idea!!
