Hogue Rubber Grip Models. What's the difference?

[Amadeus]

Hogue has three different rubber grips available for the Ruger GP100.

The Tamer Grip, which is constructed of rubber, and the Monogrip, which is made in Nylon or rubber. What I cannot determine merely from reviewing the picture is how the Tamer is different from the Monogrip (aside from the name).

IS there a difference, be it shape, angle or width? What is the difference? Thanks.

The Tamer grips have Sorbothane inserts to help cushion recoil. Like the grips Hogue makes for the S&W 500 magnums.
