I tried the BBW twice, using the procedure outlined in the BBW study .pdf on coticule.be. Of the two blades, one was harsh. On the last 3 I did (this wk), each was harsh, but more keen than I can get w/ the yellow. Once the keenness is there, the coti seems to tame the harshness - or go to another stone for smoothness. I've not seen the method in the wiki here, but now you can bet I'll be trying it.
BTW, Good to hear your experience w/ it, Alex. Thx for posting.
