Well if you want lower profile, but the same noise atenuation, go with the HGU-84! It was designed for the US Navy, and comes with either visors on a bungee, or in a hard case! 😀
I just bought a new liner for my helmet from Oregon Aero, and that was amazing! The TPL Liner was good, but this liner is superb! No hot-spots, even after 5 hours with it on (Imagine 5 hours in a Schweizer 300CB!). I also got the new earseals, with leather cover, and some kind of shaping foam inside. Truly worth the investment! I still wear earplugs, but mostly because I want to keep my hearing until after I turn 50.
Also heard something slightly disturbing about ANR as well... It can actually make your hearing worse, particularily on the lower frequencies, which I find disturbing.
