How many of you guys wear ear plugs? I'm interested in the custom molded type. Do those work well? Any idea what their db rating is? Do they stay in your ear pretty well?

I'd like a set I could use in the race car and at the range. I use noise canceling ear muffs when shooting pistol, but those muffs don't work very well for shotgun and rifle as they interfere with mounting the gun properly. Wondering if a custom set of plugs would work on the shotgun/rifle range.

Second question has to do with radio communications. I will be adding a simple radio system to the car this year. I assume you guys run the speaker and microphone inside the helmet? You don't use a speaker ear piece do you?

If you run the speaker inside the helmet and wear ear plugs... how does that work out???
