Well, lets revisit this... So I have 10 gallons of IPA that I dry hopped... One, I put the hops in after a few days at room temp and left it there for a few more. I did cold crash afterwards, hops still in the keg... The other, I cold crashed then added hops and left cold... The room temp dry hopped does have a better all around flavor/aroma... the cold dry hopped isn't too far off, but it does have a bit more grass/vegitative taste to it.. So another lesson I've learned... dry hop at room temp... Sneezles61
