I borrowed a leatt, it was the non adjustable model. When standing the brace hindered my line of sight, my helmet would bottom out on the brace, not allowing me to look out as far as I wanted. It also bothered me that I could not look down well either. Do the adjustable models have enough adjustment that this will not be a problem? Would you say the same for the Astars brace? I like the looks of the Astar brace better.
