There's been a bit of confusion between RIO's Fly Clips and Twist Clips. RIO's Digital picture shows the Twist Clip for both types of clips. As you can see above they are clearly different. Let us know if you have any questions.
RIO'S FLY CLIPS are ultra-fast, easy connection clips that allow anglers to change flies with extreme ease and speed, and prevents leaders and tippet sections getting too short. Simply tie the appropriate sized clip on to the end of your leader and either twist or clip on your fly. Multiple sizes of clip ensure that there is a clip size suitable for the majority of fly sizes.
RIO's Twist clips are recommended for larger streamers and Salmon/steelhead patterns
RIO's Fly Clips are recommended for smaller dries, nymphs and soft hackles.
