Anybody using the Napier Pro 10 ear defenders? or even the Pro 9 ? How effective are they? I own a pair of Peltor Sportac and a pair of Peltor Optime 3, but the Napier seems very practical and this for a good price. I would still continue the Peltor's when I would shoot fulbore rifles myself, but the Napier seems intresting to do some clayshooting or to walk around on the range finished shooting yourself.
