I personally like Greenlee. It has the degree of bend marked on one side and the multiplier on the other. A seasoned veteran can remember the multipliers but it is very handy for a newer apprentice who is new to bending. Also, it seems like the Greenlee grips the pipe better. One of the guys has an older 3/4 emt Ideal iron hand bender that doesn't hold the pipe very well, the pipe has a lot of side to side movement making it hard not to dog leg it. Maybe the newer Ideals are better. e57, I have never used a magnetic angle finder, are you bending angles that aren't marked on the bender? Or just looking for more accuracy?
