from my experience of doing RIS's, the recipe looks pretty good, except for one problem: Not so certain the yeast will finish out to the extent desired. I bet it does get pretty close if done properly. Maybe add some Super High Gravity into the secondary (with a rigorous starter going) when the English Ale yeast is done. Maybe Zurich Lager would work as well. May just use the Zurich Lager yeast and nothing else. Hmmmm almost time to make a RIS....
