What an excellent topic! For my part, though I've not been brewing very long, I like to experiment. So I've had a go at all sorts, even an open ferment bitter which turned out really excellent, by the way, and fermented like a flipping volcano. But I have a standard brown ale at about 7% ABV, I have a bitter that I brew often enough, and as for the rest; heck I'm doing a parti gyle this weekend comprising a strong English ale - yet to be designed - from 4.5 litres of first runnings (not sparged) and after that the mash will be added to with a load of steeped black stuff (brown malt, chocolate, and patent) and run out to the end of sparge and normalized at about 1.030 for a dark mild - with Fuggles, of course. I have no idea beforehand what either will be like and trust my senses of what should work.
