Never had a flat caused by glass or thorns (even mtn bike riding in the AZ desert) with the tire liners.
The Flat Attack sealant is new for me. I had the shop add it last time I had my velo in for a cassette change. The shop guys swear by it, even while admitting that slime, and the orange stuff are almost useless as a sealant.
Ask the guys at the shop if they think putting Flat Attack in the tubes of narrow high pressure tires is worthwhile. Your 2 X 20 and 2 X 26 Velo tires sound like high volume tires to me. I do not know what pressures they run at. Once I am done with my present tires I would also like to try going tubeless with the Gator Skins, Schwalbe Marathon Plus or like Canklecat said Michelin Protek Cross Max to eliminate all possibility of pinch flats and my nemeses valves splitting from tubes and valve failure. Can you find out if this is feasible or is it too messy.
The other thing, despite what some people say, do you believe the Mr. Taffy tire liners prevent flats. I assume you think this is the best brand. For now I would like to put Flat Attack in my tubes and run Mr. Tuffet Liners and see how that works. See what they say...Thanks,mjac
