Might sound crazy, but switch over the Buzzz. I throw rocs, zones and a stratus for mids and don't carry a Buzzz, but I throw similar ranges as you and the Buzzz will get you that extra 10-30 ft you're looking for.
Firebird would also do the trick if you've got the room for its fade.
Maybe just try to get a few more yards out of your roc. I can throw a buzz farther than roc.
And I also think Teebirds rule.
