Last year in MTK under the light i got drilled in the chest by a wave & bashed into the rocks.
Zeno was filming as my Supersurf rod had the first 2 top guides smashed. As we walked back to the parking lot to hand my rod off to Paco from Lami for repairs, I realized this situation called for a helmet. Zeno told me of a surfcaster who fished big water with a football helmet complete with facemask. No one laughs at him! later on i saw another fisherman wearing a hockey helmet. No one was laughing at him either.

If you feel you need a helmet then wear one.
Better safe than sorry.
