OK, folks, so here is the answer:
-In competition Nate Doss actually won the 119 competition, throwing just a hair under 300'.
-In practice, out of many many throws, Jeremy Koling got 2 over 300' and one of these was about 370'.
The wind was weak all day, and diminished by the time we got around the to official competition. I think that with a healthy 10-20 MPH wind it should be possible for these guys to push them out to 350', but that's a big throw for a 119-disc!
For comparison, Avery had the longest throw in the regular competition, throwing 636' with a Blizzard Boss (he was using 150-160g range). Jeremy and Myles Harding got a few throws in just under 600'.
