If you are using a D-loop, I think the only way to go is a hook- type release. I have a Tru-Ball short-n-sweet and really like it. It goes on the string quickly and without looking away. Other hook-type releases include the Spott-Hogg Wiseguy, Scott SilverHorn, Scott RhinoXT, the Jim Fletcher Insider and Fletch Hook, and many of the Carter releases. All those mentioned are in the $60-$100.00 range. I also agree that a buckle type is the way to go. Velcro can be a nightmare. Hope this helps.
