I think you are right, especially if there is only one option for Aviar. If you have different options for classic aviar, small bead aviar, and big bead aviar, that would break that voting block up a bit. But even then, I think big bead aviar is going to be the all around winner.
Personally, I like the wizard, rhino, and judge, and currently throw wizards. But when I paid for lessons from skilled disc golfers, they recommended the big bead aviar as the best putt AND approach disc for getting up and down in two from the fairway. At that time, challenger was the equivalent putter from discraft, and I'm sure others have emerged since.
Wizards were available then and I think they were well respected as pure putters and also driving putters, but they didn't offer that skippy approach shot that many pros seem to want in a main putter. But IDK for sure.
