The Bucket effect is very serious.
I understand first found when ejecting someone from a fast jet plan!!
So called the Bucket Effect due to the way it reacts like a bucket dragged through water or air.
If the chin strap and visor are not designed to break away under a certain amount of load/force the effect the simply snaps you neck like a twig!!!
Or worse case it will remove both you helmet and your head!
My limited understanding is that marine safety helmets are designed to protect from impact an intitial contact with water but under stress they sould break away.
Hence why Gecko or Comunica are the right choice.
Also a fighter pilot one would work to!!!
I would suggest not using a motor cycle type, they are designed for other types of stress and load.
