So I finally got a chance to play below 5000 feet this weekend.
Emporia KS 1207' above sea level.
My findings are now below:
Discs stability: Discs fly less stable at a lower elevation, it is that simple. I pretty much disced up a couple notches in stability (wear) and I didnt flip too much
Along w/ Stability is discs carry much further. I could throw my drives lower with less power and they would carry longer. Not only drives, but approaches and even putts. I had to adapt a straighter putt because my lob putts would glide alittle more and carry high hitting the top of the basket, or flying by.
Nose angles: discs seemed to be less sensitive to nose angles, I believe due to the less stable flight characteristics. I had imagined they would be more sensitive because the air is thicker and would lift a nose up throw more, but it didnt seem to work that way. Nose up floaty approaches seemd to be more effective as they carried further, and didnt fade out much.
Penetration lines: styles of throws that rely on penetration more than glide, such as thumbers, knife hyzers and that such fly significantly shorter due to the added wind resistance. This got me into more trouble than anything else on the course.
Tips for playing at a lower elevation from higher. Throw slightly more stable (or heavier) versions of the same discs you throw. Back off the power. Any time I tried to throw more than 80% on any line other than a knife hyzer, I couldnt control the flip (accually lost my driver w/ most sedimental value, x pred beat right w/ an ace on it) Throwing w/ the height I would throw in denver at 75% I was achieving the same distacne as I would at 95% at elevation. Its alittle easier to bomb, but alittle harder to control.
after playing for a day (of course the day of the event) I think I had a decent handle on the KS air, playing the next day I was throwing as well as I think I would have in denver. Give yourself that extra day, and use it. Oh and make rollers your bitches if you have the chance, they will carry alittle more left to right before touching down, but they are easy as hell to throw
