Bonsai Empire made a nice video of International Bonsai Master Peter Warren styling a yamadori a Mugo pine. Peter does a nice job explaining which branches to remove and why. It is interesting he did not remove all of the bark on one the large branches he turned into a jin. There is a nice close up of Peter jin-ing another one of the larger branches he took off. He also used rebar on the tree. The video is listed on the Pine tree page, under Conifers and then Tree Information.
