This is what I do. Even kevlar belted tires can get flat. Mixing those tires with a liner makes them nearly bulletproof.
I ride a road bike with race wheels on my 25 mile RT commute. I can feel the resistance in the kevlar tires more than I notice the liners. They don't weigh much and don't really change the feel of the tire.
