Bottom line...never, EVER let your airspeed get too slow, even if the clear air is close above and you really want to climb up to it. Maintain a safe airspeed(as explained in the publications) and deal with whatever consequences that are the result. The only overriding factor would be terrain. And increase the speed even more when a turn is required which must be in low bank. And keep the autopilot off as well.
