That sounds normal to more extra distance than I'd expect, depending on what Teebird you're throwing. Speed 10-12 probably won't get you a whole lot, if any, more than the Viking on golf lines, but will be longer on lower lines, on long hyzers and into headwinds than the Teebird.
I'll agree that the next logical step is adding in steps one at a time to see what you get. After that it really depends on your goals. It could be anything from going back to the drawing board or working on line shaping or just adding discs.
