None of the above. Plenty of opportunities to get flats here, and I'm not exactly a featherweight either. Gatorskins hold up when installed properly. Its a very tough tire. If these are the worst tires you've ever used, then you must not have tried very many. I still think you should consider that your problem has little to do with your tires and more to do with something else. Many of the above recomendations aren't any more puncture resistant, except for the Marathon Plus, which is going to feel like riding through molasses compared to a Gatorskin. A new tire isn't necessarily going to solve your problem..you may just end up with a more sluggish tire that is just as flat prone.
