I’m not Duke so I don’t know all the advantages of what you have pictured. Please enlighten me. I can see 2 features that may be seen as advantages by some; it is short and narrow. Is there something else good about it? It seems to me if the limbs were flipped end for end and also left narrow it would have advantage of longer power stroke and still be short and narrow. But I’m new to this crossbow thing and still trying to figure it out.
