Conclusion:
Comparison of wide and normal necked bottles has been performed from parent's point of view while no one mentions the baby-side differences like latching, feeding angle, nipple shape and flexibility. Since all babies are different and do not theoretize as much as we do the trial and error perhaps is most useful research method in this area.
