Well, I ended up just deciding to follow my own advice and I went to alex gilmore instead, and got a small asagi stone after making a request for performance over pretty (not a collector, pretty stones are nice, I'm on a moderate budget this go around). After buying a lot of woodworking stones and being happy with few, I like alex's guarantee that if I don't like this stone, no problem, just try another one. The suita stone I got from him is my favorite of my woodworking stones, though, so I'll probably not have to exercise that with a similar experience on this.
Since I can step to the razor stone from various woodworking stones that are probably in the 6-10+k grit range, I don't need a razor stone to do a lot other than be able to finish off an edge.
Still, at the time I asked this question last week, just had to check. If someone would've said "similar to the asagi stones for razors" and had experience, I might've been tempted to buy the big one from CKTG and try to make it pull double duty. AT this point, though, I already have a lot of semi-finishers in my drawer that i am stuck with because i can't in good conscience sell them to someone else as a finish stone like folks did to me - even for woodworking.
