Marathons are extremely heavy; do you need something that radical in flat protection?
Geez, I can wear out a set of lightweight road tires a lot of the time without ever having a flat. But if you're paranoid about flats then I would consider looking at the Marathon Supremes or the Marathon Almotion tires, not as flat resistant as the ones you're looking at but you're saving roughly 400 grams per tire! 800 grams or so is a lot of rotational weight being taken off. I have the Almotions on a touring bike and haven't had a flat in over 2,000 miles, but that same thing happens to me with my regular 240 or so gram skinny road tires on my other bike.
If you want a tire like those Marathons, you mentioned because you don't know how to fix a flat on the side of the road, then I suggest you learn how! You can go to YouTube university and learn how by practicing. Once you figure it out you won't be so intimidated by the process. You can also figure out how I fix my flats most of the time...I rarely remove the wheel off the bike!! WHAT DID I SAY YOU SCREAM?? That's right, I rarely have to remove the wheel off the bike to fix a flat! I simply find where the leak is at, take off about a third of one side of the bead with the hole about in the center of what I've removed, pull about a quarter of the tube out, again with the hole in the center of that quarter, patch and go. I had some old guy who lived in my neighborhood teach me that when I was about 9 or 10 years old, and I've been doing it that way for 56 or so years.
