No, although I have done both on a previous climb. From Benmore Farm it was straight up and down, a bit boring but it got the heart pumping.
If you are looking for a more interesting climb, rather than trying to do it as quickly as possible, I would start at the Balquidder side and do Stob Binnean first. It really is a lovely climb, albeit a bit of a slog (as Socks mentioned) to have to do Stob Binnean a second time. I did it in October and there were a few completely frozen lochans near the top of Stob Binnean.
