its hard to throw 500+ on a pure golf line, most holes just dont allow it. I find that the easiest way to achieve this distance is by virtue of a hyzer flip turnover shot, thrown out pretty far to the left for a RHBH and with about 30 ft of height but that really just depends on the hole, it flips up, then turns, then stabalizes, glides some more, then fades. In an open field it would be about the same, im not capable of hitting 500 without throwing 20+feet in the air. There is a hole on a course in a nearby town that is 510 and slightly downhill right near the basket so when it fades it gets a few more feet since the ground is sloping with the fade, the hole is shaped perfectly for this shot and ive overthrown it a couple times, a tailwind doesnt hurt either
. As far as which molds and how, the only molds i know for sure ive thrown that far with are Nukes, Katanas, wraiths, bosses, and a beat champ teebird (just that one specifically, not the mold in general) It takes a pretty perfect throw and good conditions help for sure, but all the times ive gotten that far out its been on that line.
