The marathon Pus and Armadillos are about as flat resistant a tyre there is and everyone deals with different hazards so in some locales they make sense but I have never felt a need to run such a heavy and slow tyre when so many other tyres offer really good flat resistance and ride out better.

The Girl has Marathon plus tyres on her city bike and this gives us peace of mind... she can change a flat but when you ride a bike with a Alfine 8 speed with a full chain case changing a rear flat isn't nearly as easy.
