It seems to me that for Sarrs and Nepenthes the general aim is desirable
pitcher characteristics - color, size, and shape. I think we are always
hoping for an outstanding and unique mix of characteristics. For Sarrs.
it seems that while some hybrids display hybrid vigor, coloration and
uniqueness sometimes suffer, particularly once you get to 3rd and 4th
generation hybrids. But --<aside> IGOR! bring the brain-- we keep
trying.
