I think the Buzz Bullets set the standard. I heard second-hand of their zone-to-man transitions on set counts, ie only transition when the count gets high. Transitioning in advantageous situations seems like a positive evolution from what I have used the last few years - transitioning after a predetermined number of passes.
Now that I think about it, some of my teams from years and years ago would transition on someone's call. I wonder why we drifted away from that? Maybe because we were trying to implement the non-audibled transition, after 4 passes, for example. And that devolved into a vocalised 4 pass transition.
The approach of the Buzz Bullets strikes me as more valuable.
The Bullets were also very threatening with their skills: sharp hucks, quick disc movement, agile pivoting, lurking poachers. They never looked like losing, despite their height mismatches against many teams.
