Those are the tires on my bike these days. They are indeed "nearing solid tire construction"! But I live in the mountains so most of my power is fighting gravity anyway, and then going downhill the added rolling resistance saves wear on rims and brake pads!
And yes they are not 100% flat proof! I had a slow leak from some bit of wire. I ride on a lot of debris-strewn roads, so I think the extra protection is worth it.
