Share 'Looking for a new putter, curious what folks are using'

I started out years ago with a "Birdie" then switched to "Aviar" a couple years ago. Lost them both somehow-Don't ask LOL. I also have a "Dart" putt and approach I'm currently using. I really like Lat.64 discs and was thinking about buying the "Sinus" (funky name), but I miss my "Aviar". Some people say an "Aviar" is a must have disc. Any suggestions before I replace my "Aviar"?
