Last year I moved my WBC super frames to 8 per box (from 9). This winter I have been moving my National frames from 10 to 9 per box, in the same way, by replacing the castellations. Where I had a few empty supers; they are now full of frames. The cost of discarding the old castellations is offset by the fact that I don't need to buy and make up additional frames as they stretch further. So 9 supers stretches to 10 with the same number of frames. Extraction is easier as there are less frames to uncap and each super will be a little heavier with the reduction of a couple of bee spaces.
How many super frames per box do others use? Or is there a better way?

May your bees read the same books as you do.
