Our deck will be travertine pavers. I am trying to decide between the Versailles pattern or just regular squares. Our PB said that the Versailles pattern interlocks better and moves around less. I'm not sure if this is true, but I guess it could be a possibility because there are smaller tiles which could help stabilize it when the ground underneath isn't totally even (it's not like tile on concrete where the concrete is perfectly even and never shifts). So, please tell me your experience with travertine pavers and patterns! I'm supposed to decide today!
