In my Proto II AC, I've got G84P(6,4,0)+BIRDIE2(0,9,1,0) and it already works really nicely with OB (then again, I was using ATLAS). If you've got G91, with it's lower calorific value, you'll heat up even less if you boost during the engagement of OB. The drain of BIRDIE2 though combined with the relatively slow refresh of G91 may keep you somewhat grounded.
