I used to use a convenient techique at an airport with nasty turbulence (due to some big hills) on the 733. Turbulence normally started below around 6000 feet. Track was aligned with the crosswind leg. Descent terminated crosswind centreline at about 10000 feet ... then the aircraft was slowed down .... descent on downwind progressively slowly and reconfiguring ... turn base gear down and flap 25 .... spin up and landing flap ... once the aircraft was slow and dirty ...1 to 1.5 miles per thousand resulted without any real difficulty. Similar procedure worked well on the Electra .. except you needed power to maintain a mile a thousand ...
