The Innova Firefly can be called a "brother to the Aviar." The Firefly has been around for a few years in limited runs, but the DX Firefly marks the first wide release of this popular putter.
The Firefly has a little more stability than the Aviar, is a little deeper, yet still has a relatively straight flight. Team Innova's Nate Sexton has loved the Firefly since release and is a big fan.
