Just wanted to chime in real quick about associating Circuit Events with "growing pinball".
In my opinion, having Circuit designation does not help grow pinball...it discourages local B/C/D level players from participating to know that pros will be coming in from out of state. What it does do is shuffle around the existing top level players by encouraging them to travel to events they might not have otherwise. There is nothing wrong with that, but it isn't growing the base of players.
As TD of the Rocky Mountain Pinball Showdown last year, I had at least a dozen conversations with local players where I found myself trying to downplay the level of competition to encourage them to participate in the event.
The number of times I found myself really pumping up the stiff level of competition and the prestige of the tournament, as you might expect, was zero.
I think the SCS is a great tool for growing pinball, but I don't think Circuit Event designation should have the same goal. In my opinion, Circuit Events should exist as an organizational tool to consolidate the highest level of competition, and to help legitimize our universe to those outside of pinball.
