Or leaks! Let's not forget leaks! What domestic HVAC contractor uses enough duct mastic, even in these enlightened days? Certainly not the boobs I deal with day to day.
Also I think you're spot on about air sealing! Even if you have no insulation at all (and I'm being quite serious here) you will do well with kick *** air sealing. Something on the order of 1 ACH @ 50 or so.
