I have since bottled and disposed of a batch of this recipe.
I ended up dry-hopping for nearly a month with 2oz of Cascade. The end result was a nice spicy, citrusy (grapefruity in particular) brew. Frankly, the batch tasted more like a 'Racer 5'. Well balanced and perhaps just a little on the dry side as far as a "clone" goes. All in all, this really is a nice pale ale recipe.
