I have both in my bag, but being a Champion/Z plastic fan, I wish Innova would release the Roc in Champion Plastic. I know, I know, they do in the limited CFR runs, but those cost to much to be a daily thrower. The Buzzz in Z plastic with an LED make a wonderful night disc.
Any changes since we talked about getting a little more distance from the Buzzz? I'm a solid roc man myself (I swear the plastic in my San Marino Roc isn't star but magic), but the buzzz is nothing to scoff at.
