I'll go with lighter / thinner arrows deal not so good and can greatly enhance the control grippers
reached by the union. In addition, with relatively heavy arrows (26g), this form perfectly for me.
The "Grip" is excellent and allows several ways to keep the dart (front / center / rear). So you can finely control how the dart hits the dartboard for example.
The quality of the arrows incl. Accessories and packaging is very good! Instead of the plastic a little nylon case would have been nicer, but in this price range that's ok like this.
