Perhaps it's a matter of keeping a slightly different angle than with the DE89 and a fairly narrow sweet spot.Update: two shaves in. With more a bit more pressure and finding the right angle, the shave was at least as good as with the EJ. I think I’ll be sticking with the Gillette. Kind of cool shaving with something around 75 years old, too.
You could always try a shim or two to widen the range of available angles, though.
