I'm all about wearing ear pro with suppressors in many cases, generally meaning shooting on a concrete apron under a metal cover. But that's at the range. All the times NOT at the range when I probably wouldn't wear any ear pro anyway is when the can is great - I hunt without ear protection, that's worth every penny.
And at the end of the day cans are no more expensive than a good scope or a decent rifle, this isn't exactly a sport for penny-pinchers if you want to play at the high levels. It was always fun to hear the rich guys at the lease I worked on dog on the costs of things like suppressors or nice scopes or all the other random things guys get tightfisted over money-wise when they roll up in a $80k diesel truck with $90k toy hauler and $30k tricked out mule wearing gucci-flague to sit in a $5k blind and schwack a $10,000-a-tag whitetail, bragging about their guided fishing trips in Alaska and how expensive it was to ship their elk meat home and oh by the way their Kudu mount is finally ready after 2 years, what a pain in the *** that Africa trip was. I'll shoot more in one range trip than they will in a decade, so their opinions about what I shoot are pretty worthless to me. But I kept quiet about all their toys because their concept of a "tip" was along the lines of "what I normally made in a month".
Makes me miss those days.
You could say my can is paid for by wearing blue jeans to hunt in and driving a 15+ year old truck. We all choose to spend our money somewhere, mine goes to nice hardware and reloading gear.
