Ridged tube bender and Flare kit should do the trick. Never had another flare tool work as well as the ridged unit. Even the little tub cutter that comes with the kit seems to hold up well.
just remember that all "AN" fittings use a 37* single flare instead of the 45* double flare used on steel type brake lines.
for "normal" size lines (3/16-3/8) i use a bender i got off the SNAP-ON truck years ago, for "big" lines (1/2, 5/8, 3/4) i made my own dies out of round stock, kinda like a mini JD2 bender die.
for flaring i have a hydraulic flaring tool that i re-cut the cone and seats to 37*
