As a player who will probably never reach Intermediate level, I would be really upset if the PDGA goes towards a model that does not include Recreational AND Novice divisions. Furthermore, I don't think anyone playing in divisions above those two should have as any say in it, unless their basis for complaint is slow play.
The real problem with baggers is unrated players. That is where the problem lies, and the solution should address that issue, and only that issue. I would have no problem with PDGA sanctioned B-Tiers and up requiring a PDGA membership in order to play. In fact, as a player and a TD, I would applaud it. Let the C-tiers still allow casual players (ie: non-members) to play as a starting point. We don't want to exclude them.
It must also be said that most winners on any given day have their best rounds that they have ever had (if they are a rated player anyway.) This is NOT bagging, as much as it might appear to be from the viewpoint of someone who doesn't know how they play. We must be careful not to assume a problem without the proper facts....which again comes back to having all the players rated.
This post isn't meant to give the final solution to the problem, but to clarify what the talking points should be.
Please don't get rid of the lower divisions. There are plenty of players who love competition that will never reach Intermediate level.
