Sir; I don't have any experience with the Tac-Pack personally. I view it as a specialty item designed as a "blow-out" kit for senarios where you have to carry your stuff invisably ( exective protection ect ). It seems to me that when you try to microsize, you are forced to compromise either in quantity or variety. I have a personal aid bag thats about the size of a large grapefruit. It is designed to be an EDC kit that can handle anything, on a remedial basis, from band-aids and splinters to GSW/knife wounds and surgical airways. Compromises have to be made as I've yet to figure out how to carry an ER in the field. I think most people are faced with common illness and injuries (thank God) much more frequently then they are life threatening situations. If you are planning to use this kit as part of your survival preps, I would offer that the minor stuff that takes care of it's self can become infected and potentially life threatening. Tend to the "small" stuff so it stays small. "all bleading stops eventually" Respectfully; Jim
