I finally got my pin to breed after months of disgust with him. Mine is an 08 at 700g or so. What I did was took him out from the 12qt and put him in a bigger 40qt tub and within 2-3 weeks he was producing plugs! Fist girl I put him to after that he locked with. Then he locked with my pastel girl and nothing since so IDK. But I too have heard that pins are a PITA to get to breed for some reason.
