Hmmm. I'm not sure that the CRK forum is necessarily the best place for an answer. Generally-speaking, the manufacturer forums are filled with harder-core fans of the particular manufacturer, which doesn't make the opinions therein invalid, but means it's not a bad idea to ask the question elsewhere, IMO. Of course, the CRK forum has been admirably brutal in its analysis of the BG-42->S30V switch.
Also, I wouldn't necessarily rush to the conclusion that, " S30V is better, otherwise Mr. Reeve would not have switched." S30V meets Chris's objectives better, but will it meet yours? For example, Cliff and others have pointed out that CRK's S30V is several Rc points lower than BG-42, which means the S30V blade will be weaker and probably more susceptible to blunting. On the other hand, depending on what you're doing, there's a good chance you'll never see this effect, and S30V's advantage in easy sharpening might be more noticeable to you. There are other considerations as well where BG-42 and S30V play off each other.
In any case, from all I've read (alas, I haven't been able to road test either), both the BG-42 version and S30V version are awesome, and if I'd decided to buy a Sebenza, I wouldn't for a second think twice about picking one up just because it was an "old" BG-42 version.
