definitely agree on the ks being incredibly uncomfortable for rocking
I use an Inox honyaki on occasion myself, although it's been sitting in it's saya for a little while as I bought a Watanabe about a month ago. It is certainly laser thin and just keeps on going. If you don't like sharpening at all, it won't care that much. It is fairly tough stuff. It doesn't take a keen edge like any carbon knives, but that certainly doesn't hold it back. I quite like the profile of the knife too. I was keeping it tuned up with my suehiro rika and it cuts quite aggressively, great for general use that a gyuto is primarily used for I guess. I let an apprentice at work borrow it and within 10 minutes he had cut himself, not being used to a sharp, nimble knife I guess. I'm still undecided about what edge I want to run on it..I was going to thin it out even more but it's probably not necessary.
If you're considering stainless knives as well now, why not consider something semi-stainless like the Konosuke HD or something? You can get it slightly sharper and get it there slightly easier than the suisin and the edge retention is definitely good enough. I believe it's also less expensive. I used a "funayaki" shaped 240 HD for a while and loved it, but I found it to be a little short on occasion for me. I'm a 270 kinda guy with prep and a 210 for service. I find 240 knives for me aren't as good as either anymore. It's a knife I regret selling, but hey, I wanted to try other things. If I had my time again, I probably would have waited for a 270 HD to come back into stock instead of buying the Suisin (but I had always wanted to buy a Suisin anyway so who knows).
