Yes the JD2 dies will do a 180 on the 180 dies, but they leave a kink at the end of the bend in the tubing. I used to have a manual JD2. I hated the kink on the 180s. Because to get a true 180, you have to bend several degrees past that to accommodate for springback.
As far as tube size, I like 1.250", and 1", but I use 1.5" wherever it fits, such as driveline hoops, link bars, etc.
