Hivemaker.
Queen Bee
I partially went down the 16x10 route to the tune of about 70 hives a few seasons ago but have decided to revert to nationals because I prefer them and for simplicity sake, the last few will be sold off in the spring.
I used to have about 30 commercial hives, long time ago now, but found the bees in the standard nationals out performed those in the commercials with regards size of honey crop, eventually gave all the commercial boxes away to our local bee inspector who wanted to change over to them, after a few more seasons he also decided to get rid of them in favour of the standard nationals.
