Alternatively, based on Yooper's advice, I've started keg hopping. I bag the hops, and toss them in the keg when I put the keg in the fridge, (which is either right after racking, or weeks/months later, depending on pipeline). The bag is important in the keg, or else the hops will clog the poppet. I used to screw around with using floss to fish the bag out, but based on Yoop saying she just left the hops in there, I started doing that.
The "grassy" off flavors you seem to get from 2+ weeks of dry hopping at room temp don't seem to happen when the beer is cold. Dry hopped in the fridge, with the hops left in, and the hop flavor lasts for many many weeks with no grassyness, and it's super easy to not worry about either racking around the hops or having to fish the bag back out of the keg after a couple weeks.
