I have been playing disc golf for about ten years now. I have decided to play competitively this year. So, I have been trying a lot of new discs and it gets kind of expensive. Can anyone tell me what internet sites have the best deals on discs? I have heard there are factory second discs that are mis stamped or have a cosmetic defect. Where can you get those? and do they really fly the same as a regular disc? Also, I am trying to find lighter weighted discs around 150 for my girlfriend. I have not been able to locate these light weights online either.
