Hi Richard,
Thanks for sharing your feedback. We're pleased to hear you liked the realistic appearance of the fly and that it helped you catch a fish so quickly.
Leader twist can sometimes occur with larger, more air-resistant patterns such as mayflies, daddies and other bulky dry flies. A simple way to reduce this is to increase your tippet diameter. Moving up to a 2X tippet will often help prevent the fly from spinning and significantly reduce leader twist.
Thanks again for taking the time to leave a review, and we hope the fly continues to fish well for you.
