Your friend is probably talking about shooting the Churchill style where you're 90 degrees to the target. You can try standing more like a rifle shooter - the leading leg forward, then try both legs facing the target. I don't think you could make up the difference you've added with just a different shooting style. You might try adding a piece of wood to match the stock, or dying your spacer black. I've added spacers and air brushed in some grain so it doesn't look too bad. There are guys who specialize in adding spacers that look real good. If your happy with the length, keep it.
