I've had a B&R for about three years. Its the 22 inch with the expandable frame. Had to use the warranty when a few screws came lose. Replaced them with heavy duty rivets, very hassle free other than having the problem in the first place. PN's look like they would work really good, but I like my bag because its not as heavy as the PN's and I should never have to by another bag in theory. I'll let you know how my plan works when I retire at 65.
