I am building a recipe for a Barleywine. However I am looking for some input on what percentage of the bill I should use for crystal malts in relation to ABV. Right now here's the recipe. My crystal percentages right now are about 10% of the total bill. Feel free to blast away on anything else you see that looks out of place.
