Exactly. Not much of a reason to think that the XP configuration would be used on this routing unless an equipment change, and the seat map when you go to book your ticket should confirm (again, unless a last-minute equipment swap). In the case of an XC/XI, you shouldn't be able to book 17H/J IIRC.
