I'm working on some box joints of various widths and looking to purchase an appropriate table saw blade. Freud seems to offer a variety of well-respected blades at decent prices. However, I'm a bit confused as to the differences in some of their product line....

The Box Joint set they offers seems perfect, but limited to a max of 3/8" wide cuts. This seems a bit limiting and I'd prefer something with more width options. Most of their blades seem to promise "flat bottom cuts", as does the Super Dado set, which also offers more variety for future cut sizes. The super seems like a better buy, but I'm wondering if it is missing anything that the Box Joint set provides...?

Also, a router is not an option...this is strictly for my table saw.

Any suggestions or comments between the Box Joint set and the Super Dado for my needs?
