Headset mounting in sparco projet

[marinetowing]

I have a sparco projet helmet and have just purchased a pair of Peltor MT632 open face headsets, just wondering if anyone on here has used the same combination of equipment and the best method for setting it up?
The earpieces seem to fit fairly neatly inside the recesses where the chin straps are fastened to the helmet and the wiring will tuck fairly neatly into the seams of the lining, it's just the boom mike that I am unsure of how to mount correctly.
As the projet only has one screw hole on each side of the cheek plates for mounting the mike I was concerned that the boom will pivot constantly no matter how much the screw is tightened, has anyone got a simple solution to avoid this?

Any assistance would be greatly appreciated.
Thanks in advance

Scott.

I have the same helmet with a Stilo headset. I have had no problems with the boom moving.
