You can leather cover a Decelorator and it will work well and look good for a pretty long period of time. It has worked well for my "Argentina" and other high volume shooting, ducks in nice weather, etc, 12ga SxS shotgun. Over time, a visible "hinge" will appear where the leather flexes when the soft pad gives with each shot. I have maybe 30k rounds through the shotgun since the leather covered pad was installed. Still going strong but for the visible hinge, which appears more like honest wear than a problem. Leather pads mount well and after some use they loose their too slick surface and become just the right mix of easy mounting and non-slip.

The Silvers pad hardly flexes and makes for the better base for a leather pad, except for the pain.

On a more serious note, I have a leather covered Silvers on my 458wm double rifle and it works well, but there really is little in the way of flex compared to the Decelorator. Don't need much flex with the 458wm if I've been keeping up with my shooting and so recoil tollerance, but if I've laid off awhile, well...
