I had 406 * 1.3" S.Licks on my Challenge Hurricane recumbent. They certainly rolled well, but since I had full suspension I can't comment on their comfort on a "regular" bike. I always had them pumped to 95 psi, I think the rating was 90 psi. In my time with that bike the tyres didn't wear out, so I can't comment on their rolling resistance compared to other tyres either.
They don't have kevlar, but there's a special second layer of rubber that's loose behind the outer casing - supposedly stops sharp objects penetrating through to the inner tube. All I know is, I biked for 18 months around central London with no punctures!
