Congratulations on graduating a size! I've had problems between sizes of domes before.... I think that its due to the surface area of the breast exposed directly to the negative air pressure.... with the smaller domes your breasts are sucked in and most of the breast is tight against the dome walls and only a small area on the front of the breast is exposed to the pressure... When you move to a larger dome more of the breast is exposed directly to the pressure... which it's not used to.... make any sense?
