Helmets are a subjective topic. But typically the more race-oriented helmets have more vision (side to side and vertical).
First thing to do is to ensure your helmet fits correctly.
I ran into that issue when I switched back to one of my RF1200's at the track after getting used to my corsair x's. I would be leaned over in a corner trying to look forward and I would be staring at the brow of my helmet (in the RF1200). Or coming up out of t5 at PIRC (leaned over looking up hill).
