Dynaplugs work. Kinda small, but 2-3 in a hole seems to be fine, easy enough and acceptable if needed.Pretty fast repair.
Stop and Go, there is one I almost forgot about. A complicated overpriced "gizmo" that has had a lot of reports of spitting out the plugs after breaking off the mushroom.
It is your money, $10 on a sticky rope kit and Slime compressor, or a lot more that will do the same, perhaps less effectively, and all either is really for is to get you to a tire change.
I don't think I would be comfortable long term with a plug in a MC tire.
Oh yea, what ever you get, use it 3-4 times on an old tire to get the feel of it. Learning curves are tough at night in remote places, even worse in poor weather.
