When you grant priority to one class of traders you are necessarily disadvantaging the other class. It seems that there is a much fairer way to do this without disenfranchising and disadvantaging market participants, and that is to give size preference for equal bid prices, otherwise Crowd Participants' 1 contract or 100 share bid will always take priority over electronic non-customer bids.
The exchange has to decide whether it wants to be a fair exchange to ALL its participants.
