SD, Mr Tuffy's tire savers work well as anti-puncture inserts. They're inexpensive and seem to work. Years ago, I used them successfully on the puncture-happy streets of New York City (and we lived in Da Bronx, mind, not the now-carefully-swept streets of Manhattan) (though even the latter weren't so carefully swept, back in the day).
With apologies, I've lost track of what bike you ride. If it's a Raven, and you're riding mostly on sealed/tarmac roads, the 1.6 Supremes have a good following (and from my very brief acquaintance, feel, well, superb and maybe even supreme.) There is an extended, ongoing, frequently funny and just-a-wee-bit-obsessive debate on crazyguyonabike on tires, especially about the puncture resistance & other qualities of various Schwalbes -- just set aside an afternoon and do a search for "Marathon Tour Plus".
Jags and Andre, there's some interesting commentary on Grand Bois and Compass Tires in the "Bicycle Quarterly" networks, and some on crazyguy, celebrating the ride qualities (comfort and handling) qualities and speed of wider tires with flexible sidewalls. I know the speed thing may not be such a priority for touring bikes, but even some of the dedicated longdistance touring riders/writers on crazyguy are arguing the case for Grand Bois and Compass tires as touring tires. (And make a distinction between Panasela and the Grand Bois/Compass variants -- as did my LBS, interestingly enough: they no longer carry the Panaselas, 'cos of too many sidewall problems, but do sell Grand Bois as a top-of-the-line tire.)
Not sure when I'll wear out my Supremes, but I'd like to try the Compass 26 x 1.75's.
