I'm trying to help a buddy out. Tonight he brought over his new-to-him '10 Demo 8. He had some kind of older E.13 guide that is clearly not going to work. What are the popular guides that work with this frame? Is it ISCG or ISCG-05? Would any models of this guide work? http://www.hucknroll.com/sunline-v1-travel-guide Also, looks like this frame needs an offset dish rim? Is that correct?
