Feedback requested on Chinook CDA

[comrock12]

This is first stab at brewing a Black IPA/CDA. I'm hoping the addition of Chocolate rye as opposed to straight chocolate malt will play off the spicy notes created by the chinook.

21% Crystal malts seems high to me. I would cut those amounts down to 0.5-1 lb. ea. and use the Maris Otter to make up the difference. Otherwise, this looks good. Post how it turns out.
