I'm starting to consider which harness to use. I know I want 6 point, camlock, pull down. I'm planning on purchasing a HANS in the near future, which require thinner shoulder harnesses. However, I'll definetly be driving it a fair amount before purchasing the HANS. Is it safe to drive the HANS designed harnesses without using a HANS? I guess this question could apply if I was driving on the street without using the HANS/helmet.
