I'm thinking too that the SAR4 might fit what you are looking for.
Curious if anyone has ever skeletonized the handle on the SAR4? I've got one of the SE variety and while it is a nice knife, the handle is insanely heavy.
Being new to Busse, I find the balnce on my NMFSH to be a bit handle heavy, so I'm considering popping the scales and grinding it with a tapered tang. I would think the SAR series would be even better candidates for it.
