I've only done this woodworking thing for six months, but I must have read two dozen threads on "which is the best blade for xxx". The Forrest WW gets high marks, as do the Freud, Ridge Carbide, DeWalt, Leitz etc. blades. I think a good blade is one that costs $40 or more. Other than that, it's dealer's choice. It probably also depends on how much power your saw has. If it's a 5HP beast, you can probably rip 8/4 maple with a rusty file.
I'm partial to the Freud blades, especially their thin kerf blades. They're also a little cheaper than the Forrest. It will take a lifetime for me to wear down all that carbide.
Lowes has some blades on sale right now, with all sorts of coupons and discounts. You can probably score two if not three blades for the price of one Forest WW.
