Kev,
I have seen the focus mitt tapes. The first tape is an extremely basic how to tape. Jab, cross, deliver knees, etc.
Tape two has you flowing from punching range to controling and striking in the clinch to takedowns to striking on the ground.
I picked up a few things, but I am doubtful a person with your backround and experience is going to learn much from these tapes. Don't misunderstand, I think very highly of Burton, but these tapes, especially vol. 1 are aimed at beginning practitioners.
