No doubt about that, but what I really wanted to get at was whether
there was any major downside to blown in over batts from the
perspective of insulation value.


No that is the only issue I know of. If I decide to add more, I will
blow it in myself. I have both in there now. The blown in stuff tends to
fill in small spaces and block air infiltration as well so you come out
ahead on the insulation end.
