It was the first recipe I ever brewed. I just brewed again as a trial run for my keg setup, but I'd like it to have a little more hop aroma/complexity. When you brewed it, did you use the oak chips? Does that add something nice to the flavor profile or not?
Cascade is great for dry-hopping. I dry-hopped 1oz Cascade pellets in my SNPA clone. Came out great. I'd skip the muslin bag and just throw in the pellets. You should be able to rack without disturbing the hop sediment. And they will float for a while then fall...
