Scott: Yes they are Ideal (my favorite) and they are the 30 degree type, also my favorite.
I never bent many three point saddles, mainly because I hated pulling through them. I would bend a 4-point more often, unless I only had one pipe to go over and the work was exposed.
if your going to use 45 degrees and (2) 22 degree bends for your saddle the rim notch on the bender is the center of your 45 degree bend ; close to it is the star for back bends dont confuse the two, hope this helps. by far the best bending guide ive ever bought is the electricians guide to conduit bending by richard a. cox 2nd edition. buy it you wont regret it.
I keep a Hickey for 3/4 rigid in my truck all the time. Use it in trenches and in dispenser sumps for nearly every new install. Sometimes its the handle that gets placed over the end of the pipe instead of the end one is supposed to use
