You don't specify quantity of chem used to process the 11x14's. I don't use the same chems as you, but when I print 11x14 I use two liters of developer in my tray. My soup of choice is Ethol LPD, which is replenishable. I purchase my chems frm either Adorama, B&H, or Freestle depending on what else I need at the time and who has it.
