Whirlpooling and the screen made by
@Jaybird have completely overcome all of my issues with hop clogging and spill into the fermenter. I now go "commando" on all my hop additions in the boil and after knockout, even with big 10 oz + DIPA hop charges. Link to

The other thing this screen does now is separate my BIAB bag from the heating element in my Spike Solo+ kettle. The Solo+ stainless basket got in the way of efficiency -- a traditional bag is actually easier to manage and better for brewhouse efficiency.
