My experience with "Black Hole" targets has been negative. I shot it out very quickly. Now I shoot alot more arrows than the average archer. Approximately 75 - 100 a day now. My best results with a target has been with these newer "Yellow Jacket" targets from Morrell. One for field pts, one for broadheads. Easy arrow removal and they last. Extra covers are also available but I have not had a need yet, and I have had these targets for about a year now.
