No, I only do a three legged pattern blind. I follow TRT2. The next step is pattern blind with diversions. You can see this sequence with a video of Hank (by Pirate). Then next is what I call taught blinds. I forget what Mike calls them. But have a bird boy go out and drop or baby toss some bumpers on a pile with the dog watching. Walk the dog off the line briefly and return then run blind. Then cold blinds.
There was a good discussion of this transition to cold blinds previously that Mike uses versus say what Danny Farmer does. I am not a good enough trainer to go straight from T and wagon wheel to cold blinds. I need the pattern blinds and blind drills.
