I asked this question in the road cycling forum. I think this forum is a better one for this question.

I have 700 x 32 Gatorskins on my road bike. I commute and ride thru poorly maintained streets.
Its time to replace the Gators. I am thinking about trying Schwalbe Marathon Plus and see how they compare. Whats your experience with the Schwalbe Marathon Plus, disregarding ride quality, just puncture resisitance.
