I'm looking for an accurate way to compare the flight of various discs, especially across manufactures. I really like innova's rating system with speed, glide, hs turn and ls fade, I am not a fan of discraft's -1.8 stability rating. I find myself turning to the flight charts on many of the retailer's websites but i find them inaccurate or inadequate; Marshallstreet compares many of the discs relatively against each other but lacks any numbers, Joe's flight chart at gottagogottathrow is all numbers but his numbers don't seem to line up with the manufacturer claims. I know ultimately the disc is going to fly how you throw it and be affected by wind and how worn in the disc is. All that said, how do you rate the flight of the different discs and whose flight cart to like best?
