well, the store/wholesaler i work for had me whip up a ratings chart for all the models currently in production.
it is available for download at: http://www.gottagogottathrow.com/catalo ... Chart1.pdf
and prints to a single page.
for models available in multiple plastics, the ratings are a weighted average.
e.g. the crush (range, high speed stability, low speed stability, power requirement)
z = 5, -0.5, 4, 5
x = 5, -1, 3.5, 5
d = 5, 0, 4, 5
overall = 5, -0.5, 4, 5, with the greatest weight given to the z model, as it outsells the others by about 7:1.
interested in feedback and comments. keep in mind the ratings are targeted with two things in mind: 1) this chart is meant for players with less than 425' of power and 2) the discs were mainly evaluated at the speed ideal for their designed characteristics.
