I've gotten used to using standard Anco (universal) style blades and prefer to use their refill inserts where I can find them. I haven't had bad results with other blades (like the Goodyear branded ones sold at Costco) but they didn't seem to work any better. Even Pylon refills worked pretty well for me. I used to find the standard Anco blades at WM, although eventually they seemed to switch to a SuperTech equivalent that had no branding on the hardware but seemed to be otherwise made by Federal Mogul (Anco) with a package that indicated that. I think WM later switched to a Chinese supplier before they stopped carrying them. Now all I can seem to find are pricey blades at $13-25 each and I haven't seen a universal refill at any discount store or auto parts place in a while. Some parts stores can order universal Ancos, but not at a good price. The one place that seems to have them is RockAuto at about $2 a pair for the plastic-frame refill inserts. I use pliers to remove the metal clip and then put them into the blade frame.
