Skinny or fat, slicks or knobby, 26" or 700, kevlar or not. The answer is tuffy liners, they will help prevent 90% of flats caused by the sharp limestone and locust thorns, except on the sidewalls there you are sol . I have seen picture nails peirce a kevlar tire, just the tiniest tip of the nail came through, it was enough to cause a puncture. Don't forget the weight of the rider plus packs, low tire presure and scrubbed (well used) tires will raised your percentage for flats. This will also affect your pocket book if repairs are needed. Make sure if you have a heavy load that you wheels are up to the weight, last thing you want is to replace spokes, anverage wheel will handle about 250 pounds.
I have a Amen for Nails but my Amen is for his first and second line on rules. I can not tell you how many times I have seen people out who do not know how to change a tire, carry spare tubes or even simply know how to use a pump or what size tire or type of valve they have. They wear all the coolest clothing and have cool gear but please...
The trail will chew up soft compound road tires causing slicing and chunking. Might I suggest a slightly harder compound like the PanaRacer T-Serve Messanger which come in a variety of widths, for both 26 and 700. This tire holds up very well on the trail and is a very competent road tire. Another one would be the Hutchinson Acrobat which also comes in a range of sizes.
Hope this helps.
