Any are better than none...so here are my 2 cents:
I ride motorcycles and had two sets of custom plugs made and they are great. One set is a full size that completely fills the ear; the other set is very small and I use them on planes. The guy that made mine goes by Arizona Al...you might google him. When I don't use the customs, I buy some foam plugs from my local Walgreens...can't remember their name but they are purple and are far better than any orange ones I have found.
Hey my ears are ringing too...not from hunting, but from my wife yelling at me for the amount of money I spent on beer at the HRC hunt test in So. Illinois.... :cheers:
DH if know anybody who works in a factory, they maybe able to get you some ear plugs like Jim was describing the ones can buy at Walgreens.
