To quote your for a 2nd time, the only reason I'm using a 44T big chainring is to work within the limitations of the capacity of the rear derailleur (47T capacity) well enough to keep tension on the chain in the granny. If I could figure out how to add a 2nd chain tensioning device to the system, I'd REALLY prefer to run something like a 52T big ring to get more top end because on my current drivetrain I spin out of 44-13 on surprisingly flat terrain. It'd be nice to pick up another 5mph or so before I spin out.
