That combo certainly doesn't sound like it should be stiff. Sometimes arrows that are way too weak will hit left too. I would try some different point weights, like a 125, and see if it gets worse or better.
Most likely though it is a form problem. You might be pushing too much with the bow arm or not getting all the way back. If your drawing hand is flying out from your face on your release or your bottom limb is kicking in toward you or the bow is twisting in your hand then you know its a form issue. Try to pay attention to the position of your bow, bow arm, and drawing hand right after the release and see if any of this is happening.
