I am glad to see the B68 back, it'll be my pick if I ever build a more upright bike than my current options - I tend to like a pretty upright-ish position but still like the bars just above saddle height. If I had the space I'd totally build up a Clem with the B68, some nice high bars, and some low gears for commuting and errands.
I will echo that the Hillborne, even the newest upcoming batch, still retains a very sensibly short wheelbase. I want to say around 455mm stays in my size. Still feels plenty responsive while being much more comfortable than bikes with 415-425 stays.
