I realize that this may be larger than what you are looking for but I, personally, love the 1600 and the 1620NF (has wheels).
One thing that I might suggest is, look at the future use and additional equipment that you may acquire. I normally take a very good while before making purchases, as I try to incorporate the future use of the product and the ROI that I may get from it. IMO, purchasing for present requirements may cost more in the long run, through a forced upgrade and/or need. Also, I love the foam padding, it absorbs far more of the shock and holds all of my equipment firmly in place. This is one of my lighting cases, with only speedlights and all of the essential gear that I would need, with this particular case of lights. The case has been used a lot and this is the condition after about 2 years of regular use. Love these Pelican cases!!!
