I have grown to really enjoy throwing putters. I use a Classic Aviar; usually I carry at least 3 in my bag. A local player taught me a game that challenges you to get all you can out of putters. Along with putter-only rounds, it has really helped boost my confidence in throwing putters. An example was during the most recent round of dubs I played. There's a short dogleg left hole that people throw stuff like Firebirds, Monsters, etc. on (I used to use a Firebird here also.) I threw my Classic Aviar to within 5' of the basket.
I can see the need for a more stable/wind-fighter/utility type putter, but for me, cycling Aviars and playing with angles covers almost all the putter shots I need. If I need more than I can get out of an Aviar, I'm more comfortable throwing a Roc for the shot. For me, the ~230' range is where the overlap starts. I'm sure if I had more power I'd probably have a different answer, but for now, Classic Aviars are working fine.
When I switch things up for fun, I also like throwing an Opto Pure and a VIP Shield off the tee. I also have a BT Hard Harp that I'm learning to use. When I first started playing, I don't think I would have imagined myself having so much fun throwing putters, but here I am throwing a putter every chance I get.
