Curious of the dryhop technique you used (when/where/how)?
I've been mostly keg-hopping for the last 2 years. I put 1 to 3 ounces at a time (all pellets in the last year) in a fine mesh nylon bag with some marbles and rack from primary into the keg, making sure to purge thoroughly with CO2.
For bottle-conditioned beers, I'll put the mesh bag through the neck of the carboy, racking to bottling bucket 4 to 7 room-temp days later. I've tried loose dry-hopping but can't get the sludge to drop out satisfactorily so I stick to nylon bags.
I've tried contact times from 3 days to 2 months (when keg ran out), and have found that shorter contact time tastes better. Likewise, I've tried different temps (40 - 75 degrees) and found that warmer temps impart hoppiness with less stemminess. I'll sometimes do a second addition, switching our the bag after 3 or 4 days.
I say none of this conclusively. It's just what I've found so far, without going to the lengths of splitting the wort into multiple vessels and dry-hopping under different conditions simultaneously. This may be on the menu in the future.
