I use the Black's releases. You give the line 5-7 twists, put the loop in the clip and snap it into place. Tension adjustable for release. Never had one come out. Even if you drop fast there is not tension to release as it will only release directly back.

Here is a link to show what they look like. Cabelas carries them also but a few dollars more.
