From what I can gather, the Rink Laminated Grips are mildly heavier than just bog standard walnut grips.

Other than that, there really isn't that much to choose between them other than price and availability. But bear in mind that, as colourful and pretty as the Rink Laminate Grip is, you'll be very afraid of altering it in any way to make it fit your hand properly in it, as it would ruin the aesthetics of the laminate.

So unless you want to spend hideous amounts of money to go to Germany and have the grip made to fit by Rink themselves, I would steer clear of the laminate one for that reason.

Just remember that whatever you choose to get, it will need to be altered to fit your hand properly by adding filler in some 'empty' areas and sanding off some other areas. Without having a good fitting grip, no consitancy can be attained when shooting.

Take a look at some of the stuff on here to help you fit the pistol grip:
