Funny thing about the Hybrid pro is that the design probably doesn't naturally protect the collarbone because they had to avoid features of the HANS system to keep the patent lawyers at bay. The HANS system would never break your collarbone.
We are right there with you Mike. Jenifer is "one with the seat" when she's on the track.This is probably the biggest reason I haven't switched away from the HANS. I like my belts TIGHT and with the HANS design there is no extra pressure on my shoulders.
