I see a picture of these on the PT website, but I can't find them listed for sale. Are these a future product? I found a review here on a prototype of this product on the hide, but it was from '09 or '10. I really need something like this to keep my Harris from sliding when I load it. The Pod Claws and custom spike type feet aren't what I'm looking for. I want something less aggressive with some surface area to support the weight.
I'm talking about the ones on the left in this picture.
