I have seen two styles of distance rollers. First is a flat, stable disc thrown on an anhyzer angle which holds to the ground, then very slowly turns over. My disc for this is a flat star katana that will roll a country mile. I also like a flat VIP world for this.
Second style is a supper flippy, sometimes domey disc that can be thrown low and flat. This disc will hit the ground earlier and with much more angle, but because of the extra flippiness of the disc will still turn up and over. It is an easy angle to throw, you aren't having to arch your back and reach back high, but it isn't a very predictable roller. I like a domey 400g D4 for this style roller.
Basically, the shape of the disc is just as important as the stablity. Sharp, angled nosed wings (i.e. nuke/crank) will curl way to the side once they get straight up and down, and more dome on the disc will mean more lift, turning the disc over faster. I definitely prefer flat, stable discs with a blunt nosed wing. Zephyrs and pa4's, because of their flat blunt wings, will roll extremely far. I have seen a 470 ft hole birdied in a putter only round with a pa4 roller.
