Red, I've never used a 4 dog but I like that the knico gets hotter faster on the surface for cooking than a thicker one. My knico is almost twenty years old and I have used it quite a bit the last 5 or 6 years having it set up in a tent for 5 months a year. I thought it was going to rust out this year so I bought a replacement, but the old one is still going strong and may last a few more years. Anyway the thinner they get the hotter they get, I think.
