Dry hopping question

I brewed up a citra pale ale about 6 weeks ago that has been kegged and is waiting patiently to be consumed next weekend. I'm thinking it would be good to hit it with some dry hops but I've been out of the game too long and I can't remember how much to use... I'm going to be using whole-leaf hops in a hop-sack, I'm just going to throw them straight into the keg... I was thinking 2-3 oz should be good for 5 gallons? Any thoughts?

2 to 3 oz should be plenty.
Cheers!

Yep, sounds about right. I dry hop my Zombie dust clone with three, so 2 if your leaving it in the keg should be plenty. If it still seem lacking after a few days, you can always throw some more in.

yummmmm. citra. would you mind posting your grain bill & hop schedule? My last IPA (VandalEyesPA) had citra in it and it came out wonderful... My friend called it "aggressively smooth"
