When shooting targets or practice I wear ear plugs plus electronic muffs, and I have never had an issue with concussion. While hunting, the long range spot and stalk type hunting I do allows me to always have ear protection in while shooting. I put a brake on my 13 lb .260 AI, and it made it more pleasant and more forgiving to shoot. Recoil wasn't the issue, though my 6 year old son can now shoot prairie dogs with it.
It's like the difference between shooting a nice Kimber .45 ACP and a comped STI 9mm major open gun. Neither one has unmanageable recoil, and fast/accurate shooting can be done with both. But the STI is a world of difference in how the gun handles recoil. Some will understand the reference, others may not.
If you frequently shoot at a crowded public range, I wouldn't. If you mostly shoot by yourself or just with friends, and want your gun to shoot flatter (not trajectory, recoil wise) and always wear ear protection, go for it. Just get a side port brake and not a radial, as mentioned.
