Dave - The Fusion isn't part of the Freud Industrial line, it's the only blade in their top Premier line...the LU80 used to be the F810 and was part of the Premier line before it got the red coating and morphed with the Industrial line. There are only two blades on the market that offer the unique design of the Fusion...the P410 Fusion and the
Infinity Super General (010-044). They have a 30° HI-ATB grind that is usually only found in 80T plywood/laminate blades offers extremely low tearout combined with the 40T configuration of a general purpose blade, a steep positive hook angle for a more aggressive feedrate, and a double side grind that leaves a very polished edge. I haven't tried a Fusion yet, but I did see a close-up demo by Jerry Coles, and it looked pretty impressive....great design IMHO. I can honestly say that the Super General is the cleanest cutting general purpose or combo blade I've tried to date, and I'd expect similar performance from the Fusion because they're so similar. Design-wise, these two are in a league of their own...you get a taste of the performance of dedicated specialty blades with the convenience of a general purpose blade. It's especially good at plywood and crosscuts, and clean rips. There's no free lunch with any design though....it doesn't rip as efficiently as a more traditional ATB blade like a Forrest WWII and can bog in thicker materials, the highly polished edges can become burned if things don't go well or with easily burned woods, and the tips may wear more rapidly than other grinds. Others like the WWII, Ridge Carbide TS2000, and Tenryu Gold Medal are also excellent, and have different strengths than the Fusion or Super General...it's really a matter of matching the blade to your saw and cutting needs, more than it is one being clearly superior.
As a bargain alternative, right now Cripe Distributing has a killer clearance deal on the
Delta 35-7657 40T ATB blade. It was originally the DeWalt DW7657 from their top series 60. 0.118" kerf, large C4 micrograin carbide, laser cut antivibration slots, made in the USA. It's really a very nice general purpose blade that'll come surprisingly close to the performance of blades like the WWII, TS2000, and Gold Medal, and is only $17 plus $10 shipping....worth a try IMHO.
