What kind of mash are you doing (temp, length, BIAB vs mash tun, expected efficiency)? Also, is it a full boil? You may want to up the bittering addition to balance that massive grain bill. Maybe up to 1 oz of magnum. I would drop the carapils too if you want to get the FG down to 1.015. You have about 6% cara-malts from the crystal and the extract is gonna have carapils in it already. You may also want to mash a little lower to counter the high amount of unfermentables in the extract.
