Thought about traditional APBT and the newer "bully" styles

I have been showing UKC standard APBT's producing numerous CH's GRCH' UWP titled pit bulls. I had always looked down on the "bully' style dogs as I felt it was an imitation. No way could u get big pits like that outta what i already had. But over the last 18 yrs I have noticed that some of my pits have been oversized and blocky. Some were short and wide and others tall and lanky. Hummmmm..... different genetics and same genetics and some many different outcomes. Yet they have all been of my breeding and my genetics. So after yrs of thought I have decided to split my lines. The stocky bully style or XXL huge to the conformation correct UKC working standard. What are others thoughts about the different types and styles.
