I think the current six have some credible following. It's not massive but the brands have been established for a decade and a half and being attached to the state as a whole, the moist casual of cricket fans have had an easy time identifying with them.
as evidenced by their current ability to pull the kind of crowds that CA is looking for.
Seriously, I went through that surveymonkey site and it was full of epic fail and derpitude. It immediately brought to mind this:
Man: How many of you kids would like Itchy & Scratchy to deal with
real-life problems, like the ones you face every day?
Kids: [clamoring] Oh, yeah! I would! Great idea! Yeah, that's it!
Man: And who would like to see them do just the opposite -- getting
into far-out situations involving robots and magic powers?
Kids: [clamoring] Me! Yeah! Oh, cool! Yeah, that's what I want!
Man: So, you want a realistic, down-to-earth show... that's
completely off-the-wall and swarming with magic robots?
Kids: [all agreeing, quieter this time] That's right. Oh yeah,
Milhouse: And also, you should win things by watching.
The only bright idea there is that it looks like they want the realistic down to earth franchise and the completely off the wall franchise to be separate. Might as well make the first club the Bushrangers and the new one the Renegade Lightning Destroyers.
