Re: Question for Dave D
Dan, Matt is correct, but I am not sure which version he has. Most likely, the first version as I don't recall running golf weight in the present version. The first version had a thin Thumtrac and was barely stable. The second version looks like a Zephyr or Birdie (current versions), and flies very stable.
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.
