First, I'm starting to fall out of love with fining with gelatin.
I've found it to be inconsistent when I follow the directions to the letter; some batches clear easily, but most take as long as if i'd not used gelatin at all.
Getting tired of seeing floaters in my beer.
And (this is the most important one) the gelatin seems to be not only be removing a noticeable amount of hop character (flavor and especially aroma) from my beers, but the beers taste "thicker" than they should.
I have beers on tap now that were all fined with gelatin, and all taste much fuller-bodied than they should be (these are recipes I'm long familiar with and should be pretty light-bodied).
Gelatin, your days in my brewery are numbered.

I've also discovered that my current stash of Whirlfloc is a lot longer in the tooth than I thought (like, several years old), so I bought some fresh tablets on Amazon.
I read that the shelf life for Whirlfloc is ~2 years; mine is a lot older than that, so I think it needs to be replaced. And the new pack will be labeled/dated so I don't run into this issue in the future.
I also read that the manufacturer recommends a boil time of no more than 10 minutes; i've been adding Whirlfloc for the last 15 min of a boil, so I will start adding the Whirlfloc at 5-10 min left in the boil and see if that helps.
Got a brewday coming up next week, so a new wave of experiments will be begin.
