3. The disadvantage of 3mm filament is finding a good filament that actually will fit through the extruder. 2.85mm is the actual size needed and most generic 3mm filament just doesn't cut it. You'll need to stick with the higher quality stuff.
That seems odd. Is there a reason why the extruder doesn't support a standard filament size? I don't mean to sound cynical but is this by any chance so that we are restricted to buy a specific brand of filament?

1. ABS can be printed in high quality on the UM2. I found it a bit more tricky to get the print to stick, but once you get the settings locked in, it does well. I prefer the PLA results.
2. The UM2 does not print flexible filament well. I haven't tried a wide array, but the one's I've tried have failed due to the bowden type extruder setup. Some people have had success printing at very low speeds with this type of filament.
