I have a set of Gentex Wolf Ears and I love them. I like being able to have almost normal hearing so much that even on very hot days when a pair of ear plugs is more comfortable I find myself throwing the plugs back in the range bag and putting the "ears" back on.
They are definitely heavier than the Peltors, but those big ear cups are essentially the same as found on David Clark aviation units and they do a much better job of sound attenuation. More rugged, as well. You can't have your cake and eat it, too.
The only negative I've found is that in the rain the microphones get wet and the normal sounds no longer sound normal, kind of muffled instead. I don't know if this is an issue with the Peltors.
That link above with the extended discussion of the Wolf Ears was hilarious! "Uhhh, maybe it uses depleted uranium?" It's just a simple limiter circuit. Gunfire sounds almost like it does on TV (this might not be a bonus
