I just bought a Skin Set from TK Photo today. Been researching and trying out all kinds of combinations and decided on the Skin set rather than the Modular.
I tried on all the components with my gear and I honestly feel (a) I need some kind of harness to help with the weight (trying out unused bag straps over the shoulder to see if that could work first) (b) much too heavy and bulky to move easily if I used all the components from the set. I would probably use different combinations for different uses. Outdoor sports events, Zoo or Bird Park, F1 etc each would require different lenses and equipment. All require the gear to be carried for hours. I have tried all kinds of bags before, backpacks, shoulder, sling, messenger etc etc. None seem to completely workable for long hours of shooting on the move. Backpacks is good for distribution of weight but useless for quick access and slings are good for access but the weight on the single shoulder is no better than a messenger carried across body. Will be using the Skin set this weekend at the zoo and will see how it performs.
