Gene, a long while back, I was trying to cut a 3-D table sitter for my wife. I was using some 1 3/4" fir that I had laying around. It was more of a practice thing so I was using junk wood. I was having a terrible time cutting it. When I posted my woes I was told to get some skip tooth or super skip tooth blades. So I ordered a gross of them from Denny. What a difference they made. They clear the kerf of the built-up dust so much better and as Larry said, you don't need or want the reverse teeth on these cuts. I did still use #5 blades but in the super skips instead.
