I thought I saw a pic of one of his bikes with those exact tires. They're decent, but they're hardly bombproof -- nothing reasonably lightweight is.

For all around riding in slop, my pick would be Bontrager Hardcases (the "Race Lite" lingo is a joke -- they weigh over 300g). Flat resistance is very good and they're cheap. You'd definitely want to swap out the tires on race day.
