I also googled it today...to be honest I am not impressed nor do I believe the article I read...they must be the easiest permit in the world....as a guide for permit myself I would discourage its use for permit here ...not saying the fly wont catch one but to me its all hype, I have fished Cuba very hard in the early 90's while working there in Gitmo...maybe they only work in Cuba because they wouldnt have a prayer here in Biscayne Bay...never even seen one in any fly shop nor heard it mentioned among permit fisherman...maybe you and others will disagree with me but since you asked...there is no magic fly or the entire permit fishing world would have it, including me ...I dont believe in testing theory while paying $$$ for fishing, I go with proven winners because time moves very fast on the water and every single cast can make or break you...you can always go prove me wrong by using it and catching one though
