D'oh! Guess I should actually read the thread before I call myself observant

Yeah I'm not at all surprised that more & more people are switching to single rings up front after what I've read/been told about how most of the gears of even a smaller 3x7 setup are just overlap. If I had known that when I was ordering parts I probably would have gone the same route & saved myself a lot of trouble with clearance issues on the front derailleur.
