OK, so I've been lazy this year. A combination of bad weather and lots of work stuff has meant I've just kept an eye on my two colonies and left them to it (so far).
I have a pale yellow colony (from GWW) in two Lang brood boxes. I have a darker colony in one Lang brood box (from PH).
Last year the pale colony took ages replacing their queen. This year they seem happy and are currently foraging like mad.
Last year the darker colony took a while to start building up, then swarmed when I wasn't watching carefully/often enough. The new queen seems to have taken over well, though, and they've been foraging well this year when the weather allowed. I've been meaning to add another brood box with some frames for honey gathering, but...
