I guess it all just depends. I use foundationless with wedge top frames with the wedge stapled on sideways so it is vertical and acts as what some use popsicle sticks for. I've yet to have the bees not draw each one as I would like. (I hesitate to say correctly, I generally assume everything they do is correct regardless of what my desire was)
However, I introduced these foundationless frames in between foundation frames, most of which were drawn already. The frames are oriented North-South, with magnetic and geographic North being almost the same at this longitude.
