Lack of intense hop aroma...

[HawksBrewer]

From what I understand, it is a chill to 160, then pull the chiller and toss in the hops and let them steep for some amount of time (my hop stands have been 30 minutes).

Awesome. So little or no bittering from this? If I take my flameout additions and do this instead I'll get more hop/citrus flavor without significantly upping my IBU?

No need to pull the chiller. Just chill below 180F, turn off the chiller, toss in the hops (I usually use around 2-2.5 oz for this addition) and let it sit for 30-45 min. Because you're below 180F there is no IBU contribution and no isomerization of the hops. This method extracts the essential hop oils without boiling any of them off. It's a technique commonly employed by professional brewers for some time now. One warning: once you start doing it you will never go back!
