What can I say? I have owned both bows briefly and I concur with Matt's comments. Both have aggressive draw cycles but both have other features to compensate for it. As Matt suggested, the brace height on the Dually makes the bow more forgiving though the drop stop on the Supertec spiral can be removed thus increasing the valley and making it more shootable.

Then you also have to consider the dual cam vs. hybrid issue.......

Tough call but I think I would go Patriot DC as well.
