Unless you're doing touring, you don't need that Plus HS440 type of tire, unless the roads you ride on are littered with goat heads, glass, and pieces of tire wires. If you want to stay with a good highly flat resistant tire you could go with the Marathon Supreme, that tire weighs around 440 grams, it will last a long time and be more than adequate for flat protection, and this tire is so good some people even tour on them. One step up from that tire with a bit more durability and flat protection is the Marathon Almotion tire, this is the tire I chose to tour on because it struck a balance between the heavy Plus HS440 and the Supreme which is more of a minimalist touring tire, but of course the Almotion weighs a bit more at around 650 grams, but I was willing to accept that since it would last longer and have good flat resistance.

Of course, Schwalbe aren't the only tires on the market, so it depends on what size tire your bike uses, you need to find something that will have low rolling resistance, good durability, and decent flat protection.
