thanks for all the suggestions!
i haven't heard any positive comments about the mr. tuffy liners, so i think i'll take the advice just to ride the kevlar tires by themselves for a while. i'll probably go with the bontrager's from my LBS if for no other reason than the convenience of being able to get them tomorrow. color me impulsive!
thanks again - i'll let y'all know how they work out.
*sdr*
p.s. ~ i looked at some armadillo's about a week ago. they seemed a little extreme. flats are part of the deal and, as i've said, i have become quite proficient at fixing flats.
i always carry at least one extra tube, patches & plenty of Co2 cartridges - a must!
