I've played NFL DFS for six years and I build software. Pylon is the optimizer I wanted: the good ideas from the existing tools, streamlined and sharpened, without the parts that get in your way.
The highest-projected lineup is the correct play in a cash game and a losing one in a big tournament. Same slate, same players, opposite math.
Contest selection moves your bankroll more than any single lineup, and picking the right pools is the clearest edge I have for steady profit.
