<I've run across a few chaps who would like the speed flown in turbulence to be far below the rough air speed in the FCOM so I am curious as to what should be flown.>
There is immense confusion about speeds to fly in 'turbulence'.
There is NOTHING wrong with flying below Vra in 'turbulence' as long as the 'turbulence' is not life-threatening. When it is, fly Vra. Reducing speed will (?always? - standing by to be corrected!) improve the ride for the salary payers in light or even moderate chop/turbulence without threatening the aircraft's structural or aerodynamic integrity. When it looks as if the bumps are getting so bad you think you will either stall or break up - fly Vra - and avoid.
