I use the same setup, without the base/guide, and have no real problems. Since I shoot in studio quite a bit, I don't use a changing bag, just clear off a space in the bathroom to lay out everything. If I'm going out for a day, I'll pre-load and label my backs at home. Takes a little practice to load the reels, and although it will hold 6, I don't load more than 4 sheets on e reel. Loads pretty easy. Here's a You Tube video that may help (it shows the base setup as well) http://www.youtube.com/watch?v=vcfTH0td9oY
