How can you "inadvertently fly into the yellow range and kiss the red
range"? Sleeping at the helm? You have to have quite a nose down
attitude to get near the red line and it doesn't sneak up on you. It's
very noisy and pitch sensitive.

Don's advice below is excellent.

A very experienced test pilot once told me, and several others, that if you
were faced with exceeding VNE you should pull as hard as you can, even if
it means exceeding max G load, to reduce speed as soon as you can to below
VNE. Catastrophic structural failures due to excess G are very rare unless
there are other factors, catastrophic failures due to flutter are almost
inevitable.
There is no right answer, just a less wrong one and I would stress I have
not had the opportunity to test this.
One of the requirements on a Grob 103 post major inspection test flight was
to operate the spoilers at 70kts, having done this many times I would not
recommend the spoilers option.
