Howdy Doody Thumbs....
I 100% agree with Mike's post. Since he lead me to the RIGHT blade I have had VERY, VERY LITTLE =FUZZIES= on the back side of all of my projects. I use 300 Grit Sandpaper....Large sheet and lightly go over the area and almost as good as the front. Yea!
I was using the profane torch for a while, but like your experience on some projects IT JUST FLAME UP and some skinny cuts just dissaperared.
Gave that up real quick. Danny :+}
