In case I flat anyway, Id like to just stick in a tube and not deal with too much sticky sealant. Preferably none at all.
Is this feasible?
The answer is "it depends" (I would think) - depending on what type of rims you are using, what type of rim tape they use, how good of a tape job it is, etc.. and how the tightly the Pirelli tubeless tires mount all could contribute to the air holding (with or without sealant). Try it and see doing a little air pressure check before and after your ride. My guess is that you really need the sealant for best air retention though.
