Jack,
I respectfully disagree. I have a LN 7 but bought a barely used Stanley 8C at an estate sale only because they offered it at a price I couldn’t refuse. My intent was to sell it for a hefty profit, but I tuned it and used it to flatten some very wide glued tops, a task which I had always used my 7. Although the 8 weighs almost 2 pounds more, it was easier to push, which I assume is because of the corrugations in the sole. The end result was the same as using the 7, but less fatiguing. I don’t use it for jointing edges and doubt the corrugations translate as well to other size planes and tasks, but for this I will always use my 8C. A specialized plane? Yeah, but I decided to keep it.
