Ehh, I'm not so sure. I, too, thought a "B" would be good, but got the "P" anyhow. (I liked the look of the control panel.) There have been times where I would really like to change things on the fly, but have found that the forced forethought has really paid off. As I buy in 10-15# lots, I do get quite a few roasts from one bean, and it takes only a few to nail down the right profile. I have settled on three or four main categories of profiles (wet processed, dry, high altitude, dark roast). I actually enjoy setting a profile and then forcing myself to just "go along for the ride." I occassional meddle with the temp setting or final timing, but usually regret it.
