Re: Question for Dave D
saint thomas, it doesn't always. Sometimes it makes the discs more stable as in the case of discs that start out unstable. Two examples of that are the Archangel and Sidewinder. Both are more stable in Pro than in DX (Archangel) or candy (Sidewinder). It's very hard to predict what each mix of plastic is going to do beforehand. Generally the very stable discs are less stable and the very unstable might be made more stable. Each disc has to be shot and tested separately.
By far, the most important part of any shot is what is happening in the last split second as the disc is pulling itself from your grip. Focus there. It's the key.
