I'm not quite sure what options you don't have at 30 degrees AOB with 10-15 knots above the stall
What you don't have is the option to tighten up the turn, or climb. In level flight, at 30deg bank, the stall speed is already some 7-10% up. It's a bit like on a motorbike; when banked over hard, you can't brake
You are already likely to be relying on it being a descending turn, to keep the stall speed in check.
So when going to some free-for-all airfield I would prefer to do a larger circuit and fly a longer final.
