I happen to come across this tonight trying to compare a Discraft Crank with a Latitude 64 Gold Flow. Yea, the one that "walked" away with someone.
http://infinitediscs.com/home/A very informative link whereby one can compare different manufacturer's of the same disc type.
For example, don't select a Brand, but select a
Disc Type, and
Stability to get an idea of what discs are available per your selection for all the available manufacturers.
Then select additional criteria based on your desires to minimize the choices.
It's pretty cool. Saves a lot of time researching all of the different charts of each manufacturer. I hope you find it useful.
