I've been running full 3/32" fixed gear drivetrains for longer than many posters here have been alive with absolutely zero problems. All my old road fg rigs have been geared road bike conversions using road chainrings, many with non-optimal chain lines. My Wabi Lightning fg has a full 3/32" drivetrain, and runs seamlessly. I think there's a lot of hogwash factor in threads like this one.
