I should have mentioned that I was talking about tubeless tires only. Based on my experience with tube-type flats in the '70s and '80s, the only fix for those on the road is usually to install a new tube. I used to carry a tube for the rear and enough tools to pull the wheel and pry the bead off the rim. The front never went flat on any of my bikes. That reminds me, those bikes all had centerstands that would put the rear wheel in the air while I was fixing it.
Regarding patches on tubeless tires, I have no interest in riding on a repaired MC tire any longer than it takes to get home or to a bike shop. So, regardless of how the tire is temporarily reinflated, I still have to replace it. That's why I'm leaning toward the simpler method of just carrying a can of Flat-Fix.
