p.s. Of course about the grain bill, if you do attenuate more, it means more alcohol so you do have to lower the grain bill a little bit...
I assume this was in response to my comment.
The reason I recommend lowering the grain bill is that if he is going to have it finish at a 1.022, his RIS is going to be even stronger. When I make recipes I shoot for an ABV number with a FG that fits the recipe, and then build up to the OG from there.
I'd mash this RIS at 152-153 to have a rich mouthfeel. Going too lower would make this too thin for an RIS. With a different type of beer I would go as low as 148, but not here.
You're right about WLP002. Getting it to drop a beer .080 gravity points isn't easy...that's why I would drop the OG. His current recipe is solidly above the halfway mark in ABV for the style, and dropping down to a 1.095 OG won't hurt the beer. If anything it will end with it being more drinkable since WLP002 should be able to drop it from there to a 1.020-1.022 without too much coaxing.
Side Note - This is what I love about brewing, so many ways to end up at the same destination. For instance, if I had a yeast cake of WLP002 from a Bitter to dump this on, then I would absolutely leave the OG up there. It would finish low with that big of a starter, and I'd have a nice 12%er to age on oak for a while.
