Here's what Innova has to say about the Dart:
The Dart is a small diameter putter with a straight flight. The Dart is especially good for long range putts and go-for shots. It has a flight similar to our Aviar Putt & Approach but has less low speed fade and a little more range. The nice thing about this disc, besides the improved grip, is that it holds the line for a long time.
Speed: 3 Glide: 4 Turn: 0 Fade: 0
