RE: Need a release with a short head
I was afraid of the 'peg style' Rhino until Matt properly introduced it to me a few years ago. Like Matt, I've never looked back. The other releases are that have been mentioned are worthy as well. It's all in what you're trying to accomplish.
With that being said, if your DL is too long, it's TOO LONG. All you're doing by grabbing a shorter release is changing your release hand anchor. You might still me missing facial anchors with too long a draw length. While I mention to many that loops don't change your draw length, shorter releases will also not accomplish this task.
