Flew the MARNR arrival early this AM. It is a STARR not a visual RNAV. It starts over Victoria then has a more angled approach (from the north) instead of a 90 degree turn to base from ALKIA. It worked pretty well, were at idle from YYJ to 1000' but a couple of the steps were a little steep and couldn't hold the airspeed so had to use the SB a little, that was with a crosswind.
I think PHX is about one of the worst actually. On the MAIER from the north, you're about 10,000 to low the entire time. Just because it has the MOST stepdowns doesn't mean it has the best.
