Let me start by saying that both of these molds are great and either one will help you make a great stone. I have used both the Slater’s and Hybrid stone molds to make atlas stones for myself and other gyms. If you didn’t know already, you can’t simply go online and purchase a ready-to-lift atlas stone (the shipping alone would be prohibitively expensive). You have to get a mold, follow the instructions, and build one yourself if you want to get going with this effective method of strength training. With that said, there are some key differences between the available molds that will help you decide which product is best for you.
