Good topic! IMO "ultralight" is a relative term as each rod manufacturer is different. I don't worry about feeling the fish bite, because gills, crappie, and the othe bigger species don't usually hit raps light. I'd rather go with a stiffer action (fast action) tip to give me power to control the weight of the rap, control the snap, and set the hook. You really could get a away with using the same rod for 1/2 pound gills as you could 4 pound eyes (#2 to 5 raps). Lower end rods that work, the list is very long (my cheapos are Genz sticks), and my higher end rods are customs with St. Croix blanks. When those break, I'll be switching to the Sweathearts, which are ridiculously good rods. Bret can tell you the action/model.
