I have an all Discraft bag and it happened on accident. I used to throw mainly Innova because of the availability of lower weights, especially 150 class but since I have learned to throw in the past year and half I have less need for the low weight. I bought a misprint deal of Discraft from Sportdiscs.com and fell in love with a couple of discs there, then when FLX plastic came out I bought a bunch of that too and one day I realized I didn't have any more Innova or Lightning (yes I used Lightning, SHUT UP!
) in my bag and I haven't really gone back since. I make a lot of jokes with people about it but I really don't have much of a bias other than I am more comfortable with Discraft and their molds at this point and it's what I choose to throw. I am experimenting with a Pro Katana in the field right now.
