But jaw fatique was absolutely an issue. Don't know exactly how you'd resolve it.
Make a
chin rest for the DSV/BOV goes a long way to help jaw fatigue.
I scootered a lot with the KISS BOV, and had Gordon made me an extended SS bottom plate (look at the SS plate goes around the switch on bottom) to replace the original. Then bend the extended lip to fit your chin.
This puts the pressure on the chin when scootering and prevents the BOV from being rotated from your mouth.
Same idea could be applied to other BOV.
I am scootering with the Golem BOV now, and adding a small foam pad on the inside of the 2nd stage to rest the chin on.
