get the 240* dies. always nice to have the ability to bend sharper angles than to be limited by your die.
and the CLR (center line radius) depends on what you are doing and personal preference. I use a 1.75 x 6" CLR die. it is nice for stingers and general fab, but when doing interior cages a smaller CLR would be handy for working in the tighter spaces.
