Fishboy. I agree, I had a birdstike in a gazelle a few years ago. A sparrow got me right between the eyes. Luckily I had just put my visor down. I was sat in the back at the time. It went between the two crew in the front without touching them and I was covered in bird guts and perspex.
I was flying the above mentioned cab!!!!!!!!!!
Seriously thou............ do you need a helmet. NO is the answer unless your flying military aircraft.
Relax with your head set and shorts man!
