I got a small 21 as my 2nd, but I think a small Inkosi would complement your new 21 nicely. I personally like the insingo blades, especially in the smaller CRKs, I feel like it offers more usable edge for general cutting. The small 21 is really nice too--slightly more blade and a slightly bigger handle, but still quite small compared to the large. The Inkosi takes the classic Chris Reeve features, vault like lock up and hydraulic action, up a notch, and it's got a bit more heft than the 21. I don't have a small Inkosi (yet), but the large Inkosi is my favorite CRK at the moment.
