No mate, only made 64”, 66” and 68” in the deflex/ reflex. Very little blind hunting here, so not as much call for the shorter length bows. In saying that the 60” forward riser I made for myself, has me infatuated! I think a short riser like your 12” would be a bit small for my huge hands. Loving all the experimenting you have been going. I have been following usually without commenting much. You have built some very good performing bows! Great stuff!
