I have some T3s on the way to me. I read several comments that if you don't plug some of the air holes you get mostly air. Suggestions on this?
2 ways I use
a toothpick put in the hole then carefully snap it off so the hole is filled with the toothpick tip
also hot glue gun , again using a toothpick, dab some glue on the end of the tooth pick and fill the hole with the glue on the toothpick
Do one hole at a time (there are 3 holes I think) and see what works for you as far as how many holes you want to fill
