I forget who it is offhand (oldtimer's disease) but I know at least one member has the 15 and 20k Suehiro. Personally I just "think" the 15k is an unnecessary step in the progression, but that is just what I think, not from hands on experimentation. If you've got the $ I would say a naniwa superstone 12k would be a nice jump. Then, if you still want to go on up, the 20k is the cat's whiskers IME.
Chrom-ox is good stuff. I've used it on felt, and on leather. I don't use it often because I have the high grit finishers and I can't see using a nickels worth of powder on an edge I've just honed with a $250.00 stone. If I'm shaving,doing a first pass, and I feel like the edge could be smoother I grab my SRD modular paddle and do 10 light round trips on chrom-ox on felt, then another 10 on the scrub leather on the flip side. That gets me to the second pass, and I put that razor aside to touch up on the hones. IMHO.
