Sorry - we are off on a 737 trail here
I 'grew up' on the 737 with Captains who threatened to remove my left arm if I used it at more than F5. I now do the same.
If you ever have the chance to sit at the back of a 737 when some ******** up front cannot control his speed without s/brake at Flap 5 or more try to watch the tailplane - I almost guarantee you will never do it yourself again. It is worth asking the rear c/c too if they notice the heavy vibration.
