As stated, type of wood isn't important and you have good information already to help you decide on what kind of blade. If you want good accurate cuts, you need to follow more instructions as setting the blade height on your ts. If you crank up your blade all the way - as high as it goes - and try to cut a 3/4 inch board, you will have serious tear out because the blade will be exiting the wood at a sharp steep angle. If your blade is not high enough, it will be working too hard, heat up and cause burn marks. That's the basic rule. As for details, they can be controversial. I take my stock and lay it along side of the blade and I will lower or raise the blade until the bottom of the gulleys are even with the top of the wood. I get smooth cuts and the blade works the way it was designed too.
