Got Omniums from your shop when you had them on sale, just wanna say thanks for the great deal!

Now my question: I'm building a 722ts. The BB shell has been chased/faced, BB installed to spec, mavic open pro/formulas are on their way... should I expect any chain line/spacing issues when I go to set it up? Can't seem to find a clear consensus... some say you need spacers, some say no.
