Used a cheapo Walmart tire plug on my Virago 750 and a while back and rode for several thousand miles on it w/out troublw.
Recently had to use my BMW plug kit on a brand new Conti TKC-80. Still running the same tire after quite a few mile of hard Colorado off road and havent had a problem. Haven't even had to adjust the tire pressure.
My 2 cents: plug the tire and just keep a close eye on the patch. Visualy inspect it before each ride and spot check your tire pressure more often than usual. You should be OK.
