I was originally thinking of going that route since I always wear a HANS when on track. But a few things changed my mind. Taking a walk through the paddock/pits I didn't see any pros that were using the 2" shoulder straps. Next I figured in the event I let a coach or someone else help me shake the car down they would need to have a HANS in order to go on track. The 3" leaves me with more flexibility in that respect. Third reason was that the HANS was specifically designed to work with the 3" belts. According to the company they will work with either 2" or 3" but the original testing was done on 3". I figured if its not broken, don't fix it...Do those have the 2" shoulder straps to work with a HANS?
