Show us the pictures mate, it would be great to see another system in action. I think all this might come down to what scooby is saying - horses for courses. You have the system that suits your abilities, style and location at the time. I like the 2 line because I have almost zero risk of dragging the spin and suits how I organise myself (badly) at roundings. I might go back to single line as I get more polished who knows, or if someone shows a killer system on here!
