I think it was suggested following the Dan Air Tenerife accident, had the aircraft made a wings level climb rather than a climbing turn, the aircraft would have cleared the terrain.
Also, yes some civilian circuits flown are unusually large, especially if you have an engine failure downwind or on base.
In answer to your originak question, 15 degrees in the climbing turn and all other turns 30 degrees. Flaps in the turn like sideslips in the turn should be exercised with caution, likewise sideslipping.
Should anyone be interested in the possible outcome of excesive bank angle and possibly sidesliping onto finals, the fatal accident of Chipmunk G-BDID serves as a warning.
