I started with the Aviar, lost it within a couple weeks. Got a birdie, didn't like it. Got a dart, but it wasn't that comfortable to putt with. It's a decent approach disc, though. I ended up giving it to a friend who loves it. I then got a KCP BB Aviar, lost it within a couple weeks. Then I found out about Wizards. These have been my go to putters ever since. I tried out a Star Aviar driver as a driving/approach putter since I wanted something a little stiffer, but like every other Aviar I've owned, I lost it within a couple weeks. I don't know what it is, but I can't seem to hold onto an Aviar to save my life. I just ended up getting a couple more Wizards in a stiffer plastic for driving.
