The grounding is only for Mediums with Airwolf straps now. 
interestingly it looks like the Airwolf 2 year calendar life strap part number that failed.

That was always the issue with them and Bell, that they wouldn't increase the 2 year life. 

Airwolf make a 3 year life version so let's hope it's not a miscalculation on the time-life.
