Nice start to a becker. It took me several years to finally get one. Can't say it's my favorite knife, but it's a lot cheaper than the one I call a favorite (ratweiler, FWIW) and lets face it, it performs nearly as well, if not just as well.
I'm biased, but get a BK62 and you can just sell the rest of your fixed blades if you don't feel like having tons of options (but that's 90% of the fun). BK9 = all-purpose big knife and BK62 = all-purpose knife. Maybe throw the BK16 in there, though I prefer the clip point, thus the BK17 (which I haven't used because I'm too afraid to get it dirty after the long search... shame on me, really).
