I like your razors! I want a puma. Thankfully someone sent me a Puma to hone, so I might be able to nip my budding desire in the bud.

As for the 8k, you are very convincing. I keep forgetting that I used to shave off an 8k stone and it was pretty acceptable. Now I can't live without the finishing stone, but your absolutely right. 8k will shave and shave pretty good. I'd give it a C+ grade or B-.
