I have a DW735, and it is a great planer. I had been using the Infinity Tools carbide blades, which are better than the stock plain steel blades. But when I made all of my kitchen cabinet doors and drawer fronts from maple, I had a lot of tearout due to the grain orientation, and streaking of the planed surface.
I decided, after watching some videos, to invest in the helical cutterhead. After looking at the Shelix and the Lux Cut, I went with the latter. Had to wait a while to get it, but put it to use on my Sapele plant rack I just did. That thing worked incredibly well. Surface was perfect, and sapele is pretty hard wood. Dust collection is much improved as the pieces are so much smaller than the shavings that come from the straight blades. It’s expensive, but if you nick a blade, you just unscrew the damaged cutter, rotate it 90 deg and put it back. With the Infinity blades, you had to buy a whole new set.
