I've always had good luck with Victor string plugs. Sometimes the hole develops a slow leak and has to be plugged again. No big deal, especially if you carry an air compressor. I did have one larger than usual hole that kept leaking. Stop and Go plugs are supposed to be better for larger holes, so I bought a pocket plugger and keep both kits in the saddlebag. I always run my tires until they are worn out, even if they have been plugged.
