I don't have a bender but the die I would like to get when I get one would be 1 3/4 180 with 5.5 radius. I can't see when I would need to bend more then 180, but the 240 would be good because its there if you need it. I would get the 5.5 radius becuse it is smallest radius and could get tighter bends. I would also get one for smaller tube for fenders and such. I know a lot of people use 1.5 for exo's
