Given the choice always use internal patches over plugs but patches won't work at all close to the side walls because of flexing. The "hole" is only as big as YOU make it (unless the FOD makes it too big for even a plug). Once you get the tire goo into your tire pressure sensor and tire air valve they are history and need to be replaced. The goo/sealant makes a mess and is not easy to remove. If left in the tire it can solidify or freeze and cause tire balance problems. Ask your tyre supplier what they think of the sealant. But to each his own.
