I'm looking to upgrade slightly on a bag (currently I own a $13 Lightning Starter bag...). I'm not looking to spend over $50 on a bag. I need room for about 11-15 discs. I have been mainly looking at two bags that are around $30: The Fade Crunch bag (http://gottagogottathrow.com/discgolf/fade-gear-crunch-disc-golf-p-1674.html) and the Discraft Tournament bag (http://gottagogottathrow.com/discgolf/discraft-tournament-disc-golf-p-332.html). How does the structure and durability of these bags compare to others in this price range? Do both of these bags have a structural frame, or are they purely fabric?
