I suppose one could use Tuffies with the Marathon Plus if you are still getting flats. I don't.
I ride nothing but Marathon Plus on my commuter because I have yet to try anything that comes even close (Armadillo is nowhere near the MP in terms of flat resistance IMO).
However, there is no such thing as a flat free tire. I've had 2 flats with my MP's, one last night. My first flat was a nail that would have gone through a car tire. The one last night was different. I went into some blackberry thorns, and one of the vines got me through the side (so the tire liner wouldn't have helped).
The MP has a good ride and it lasts longer than anything else. They're spendy, but they're a good deal for what you get.
