Thanks all for your input. The senario as stated in my quest has happened to me several times whilst flying Condor - Glider flight Simulation software. I've been deploying spoilers to slow down but that I would ask this group in case it happens in a real glider. Your inputs, as I suspected, are well thought out and are convincing. My thoughts to control highspeed flight (overspeed flight) will be pitch.
Illustrating nicely the perils of self directed training in Condor. You did well to ask for the benefit of real world experience.

Yes, good to ask real world experience. While I've never been in the scenario as described (over VNE unintentionally) I have had dive brakes open at speed.
Coming back from a day of flying, I did a speed pass over the field (in a ASW-24) aiming to do a pull up and enter late downwind. At ~300' (in the pull up), I hit a gust that slammed the spoilers full open (speed was likely close to 180MPH) and aimed away from the field.
The glider felt like it hit a wall.
I went from, "Life is good, lets do a nice pattern" to "I'm low, losing speed quickly and am getting a wee bit busy".
The spoilers DID close and everything turned out well.
We did spend some time checking spoiler linkages & alignments before de-rigging.
As to flutter, I would hazard it's more of the control surface balance, hinge condition & linkage slop than the wing itself. The wing tends to be involved AFTER the control surface flutters.
Right on up there with old/cheap safety tape that peels up its leading edge and blanks a surface. Especially newer designs with small chord control surfaces.
