Yes, get an edge for 3D its the best no question. It is not fair to say that an edge sucks based on what u have experienced with the Hanger 9. I had a hangar9 and it sucked.
Welsh3d - The reason you see more extras than edges at TOC is because TOC is IMAC. The only 3D they do is in their freestyle, which is only a small fraction of the total amount of flying they do while at TOC. An extra is better for IMAC and an edge is better for 3D...period.
