this is a great chart worked up by blake t from discgolfreview.com
i have found it reflects realistically how most discs fly more than marshall street on average....but i think the best results can be found by comparing those two charts....and probably some of the others i am less familiar with, when actually throwing/fondling the disc may not be an option! Both charts do have some errors or inconsistencies though imo.....
