These are probably the best stone molds but I feel like they are incredibly expensive. I think the hybrid ones might be a better option since its just a big plastic globe. The stickers fall off basically instantly. I like the the hybrid molds have the indentations.

I’ve got multiple sets of Slater molds. While I’ll start by saying I’ve not used any other stone molds I’m not sure how you could get a better, easier to use stone mold than these. If the mold is prepped, assembled and poured correctly the stones turn out pretty darn nice. The stone is left with almost no indication of an equator or line in the stone where the two halves of the mold are joined. Clean up is also simple with them if you follow Steve’s recommendations on mold prep. They seem very durable if taken care of properly. Take your time prepping your mold and I think you’ll have great results.

Great molds and the fact that Steve will help anyone build better stones is exactly what the sport is about. Some of my molds have probably had 20-30 stones through them with 0 issues. Molds hidden under the Hammer Jammer in pic

I have the 18" 240 lb mold and it has been great! It wasn't too difficult to build and the results were outstanding! I'm ready for the 20"!

Slater is the stone and log king. These are well made mods that are easy to use. Follow their instructions and you will get top quality stones. Their mods vs others just make the process a bit easier.
