They can both shoot with a "backwards" stance?
I saw Jayson on the stream today, shooting a short shot into the upper left pocket, but, being left-handed, he didn't have an easy stance. He turned his shoulders as if he were going to shoot right-handed (left shoulder forward), but instead tucked his left arm across his front side (elbow near belly button), bridged with his right hand, and took the shot from that position...
I can't say I remember seeing Ralf do that, but it certainly caught my attention as a unique skill.
