No, I suggested a 356-seat Parliament with 210 constituencies and 140 proportional seats. That's a two-thirds ratio, and that would certainly increase the size of the constituencies, but it wouldn't be as bad as if you had to cut them in half.
I sympathize with representatives who have huge ridings to represent, like Nathan and a few others, Matt also. I sympathize with them, but if you're going to have a mixed member system, that's going to be inevitable.
