You didn't mention whether the bow was of symmetrical design or if the top limb was longer. You also didn't mention whether you were pulling from center of handle or pulling from where your string hand will be pulling when you're actually shooting it.
If the latter, I would tiller the bow so that the nock point comes straight back, not favoring either limb. That will produce the nicest drawing, most forgiving, inherently tuned bow, with the least handshock. If it ends up with negative tiller, so be it... that's exactly what it needs.
