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.

Since flutter is a dynamic phenomenon related to wing stiffness, I could make a theoretical argument that loading the wing would help. But I am not going to test it.

There are a lot of pilots flying up in the mountains where I fly that are unaware that just because the placard says 146 knots IAS or whatever, that is not true at FL180. On my glider, 146 knots IAS at 10,000 ft, 122 at 18,000, 76 at 42,000.
