I have always used high quality blades and had them sharpened regularly. Recently, the local Woodcraft had a demo by Ridge Carbide Tool. I learned a great deal about the engineering of saw blades and correct setup (ESPECIALLY THE BLADE HEIGHT.)
I purchased their 40 tooth "Super Combo" which was recommended for segmenting. I don't know if it was the blade quality or the correct setup, but the cut was great. The cut surface was equal to my Kapex 80 tooth (my normal segment cutting method.)
My words of wisdom (.02) are: find out how to correctly set the height of the blade; keep it sharp.
