Adding attic insulation
While your crawling around adding the chutes and batts, add a tyvek air barrier on top of everything as well. Air movement within fiberglass batts greatly reduces the effectiveness. So if you put an R-30 batt up there without an air barrier, then you only really be getting an R-20, or so gain, as the top layer of batts will be compromised do to attic air movements. So, for the $150 or so that a tyvek roll costs, you'll reclaim that lost R-10 or so.
Life's too short...so enjoy it!
