You, sir (or madam), are making me thirsty. That looks scrumptuous.
I've dry hopped like this, but it seems that the hops on the top of the pile, and really even the ones that are in contact with the wort but not submerged, are not contributing to the beer, or are only partially contributing. After a couple weeks of dry-hopping with whole flowers, I usually cave and use a carboy brush to shove the flowers down and get everything soaked. Then I drink a beer.
What say you?
