Nose high speed decreasing unusual attitude/upset.
You can use roll to aid lowering the nose if you have a very high nose attitude but only if you have sufficient speed in hand in the first place. Interestingly Boeing advocate up to full nose down elevator and a REDUCTION in thrust to aid recovery. The order is elevator, trim, thrust, roll and the roll has a caution attached as does the use of trim. By using the elevator aggresively your decreasing your angle of attack and making a stall due to roll much less likely (you can't stall at 0G) and reducing power will aid the pitch down initialy.
If your 40 nose up in the stick shaker then I'd reckon you don't have that speed in hand and by rolling your going to increase your angle of attack on one wing so could easily induce the stall you wish to avoid and make your subsequent recovery harder as the stall on one wing could induce even more roll. If you want to see that in action then look at the video of the Nimrod crash during an airshow in Toronto, I imagine its on U tube. Not exactly the same as they were in an established turn with G on but it gets the point of Mvr stall accross in a very tragic and poignent way.
With 40 nose up and stick shake you'd be doing the approach to stall checklist I would imagine. That and praying to whichever God you happen to believe in.
Out of interest in the air force with nose v high, speed low and rapidly reducing we were always taught to go to idle and centralise everything, wait for the aircraft to fall out and once speed was on the way back up effect a recovery using nose low techniques. Not as a technique in the QRH or the FCTM though.
