My tastes with medium light are flat big burrs I have in my major, they just give better separation of flavours Vs the conical in the niche
This doesn’t mean the niche is bad, it’s just more muddled.
The problem with lances review is he’s is a light roast guy, and put this through a set of burrs the kony burrs that were not ment to be used for light, so he’s going to have less favourable results. I note he doesn’t always use light roasts in his grinder reviews….
