BBS-1 is a gem. Trust me.
Why don't you wait for the WR2 head? It looks similar, if not the same, to the BBS-1, although he won't offer it with the known BBS-1 handle. Won't be numbered as well or engraved with the LASSC logos, but I have a feeling that it will shave similarly( if not the same, again).
If you're a collector, then yes, go for the "original".
