Great meeting you guys on Saturday.
I have repaired tire both ways: a plug and an inside patch. I've used the plug method when on a long ride days from home stuck on the side of a trail miles from anything. I've used the patch method (better method) when I went out to the garage to find a flat tire with a nail in it. Both punctures were small, round, and in the middle of the tread. Neither tire leaked.
I worried about the repairs until I forgot that I had done them. I remembered the repairs when I replaced the tires several thousands of miles later. Motorcycle tires wear out so quickly that the repair will out last the tire.
Two exceptions. 1. High speed use like racing or long, long highway rides at speed. 2. Any damage close to or on the sidewall.
Personally, I would inside patch the tire and try my best to wear it out. If I was headed for a two week ride out to California or the race track, I would replace it for peace of mind.
