gotta throw discraft. their midranges are the best (buzzz, meteor, wasp). My favorite disc of all time is the predator. Discraft has failed to dissapoint me. they also have the best overstable discs (pred, xtreme, certain forces, zone...). however i do like the Xcaliber. but gateway putters are the best. my main putter is the magic, but i love the wizards for short drives and longer approaches.
I suppose I carry 50% innova (90% of drivers) 40% discraft (all putts, mids) and occasional millenium.
Innova for drives- larger variety, more suited to high-power big arm throwers
Discraft- for consistent control midranges and the best putters (not a fan of any Aviar, ever)
I'm new to the game and my drivers and mids are Star Innova, but it didn't take me long to find out that after I bought my Gateway 172 gram chalky Wizards I no longer needed my Aviar Driver Putt and approach. The Wizards simply do the same thing better for me. I did however do a full on drive with the Aviar P&A once and it did what my San Marino Roc does oh so well.. but just not quite as well.
I throw more Gateway then anything else, But I also have Quest AT, Discraft, DGA and Innova disc's
I think to limit to one brand it to miss out on a lot! No problem with a favorite brand but I know people that would not even take a disc from my bag if it didn't have the right brand name on it. But you could have another brand hot stamped on there and say it was their brand and they would love it before they throw it!
I say love the disc not the brand, if the disc does what you need then it's the right disc. How are you to know if you never try?
