Sounds like you might have a twisted limb. What I'd do is swap them top to bottom and vise versa and see what happens. If the results aren't satisfactory then a call to Joel might be in order. I've found that any of the binary cammed bows exhibit a touch of cam lean (limb twist), but not much. Laying an arrow along the cam extended down the string I get about 1/4" of lean at the nocking point.
