Over the last year, I have purchased enough elements for two complete setups. One will be used for local electronics transport. The other set will be used for travel purposes. There are enough pockets to carry all of the support items I need, plus many other items. I have all side pocket styles and center section bags and have used all combinations. I am never wanting for space. The only thing I have purchased, but will probably not use in the bag carrier - it is very large and bulky; I have assembled materials to build my own carrier that will integrate with the bag and not add excessive bulk nor have to be removed, ie, it will still fit under the seat in front of me on a plane. I highly recommend the Brightline bag system; I will never need any other system at this point.
