Yes, I have huge issues with closed down ear canals from surfing and sailing in cold air, and I'm only in So. Cal!! I also shaped surfboards and my right ear has some damage from the high pitch of the planner cutting foam. Both of my ear drums are also scarred.
Most plugs are horrible, they just don't work for many reasons, except some Spanish ear plug that are from Barcelona called NOHISENT, they are cotton and wax and can be adjusted so when your driven down you can still equalize without water getting in. I've used them in cold Cal and warm Hawaii and they worked well in both places. It took awhile to get used to my hearing being muffled and having to compensate for the reduction of that important sense but the discomfort and downright pain of water trapped in my ear for a week or two has made it mandatory that I use plugs or quit surfing (not an option!!)
