Here are some photos for reference. Notice in the third photo, DCXL. He's Very low to the ground, but lots of traps. This plant is about the same size today, height and trap wise, as it was when I purchased it in April or May. Jaws is in the 4th photo. He has nearly quadrupled in size since I purchased him around the same time frame.

My guess is, there are certain traits in certain cultivars that appreciate, perhaps, a particular aspect of it's conditions with the original grower, that may not show up in the conditions of another grower.
I still love my plants, and appreciate their uniqueness, such as their coloring or their vigor. I bet there are 20 other folks on this board that can show you the opposite in their experience.
