Bags rock! They're inexpensive, color coded, semi water and mud proof, easy to throw in your trunk, backseat, pickup bed, etc, keep the rope knot, kink and tangle free, and easy to haul up the tree and drop down thru the exact set of branches/crotches you want. Modern ropes don't develop memory the way the old 3 strands did when they were coiled, but bags still keep them the most limber and flexible.
I still coil a few of my oldest, lowest ranking ropes that only get used a few times a year, just because they're not worth buying a bag for. You mentioned "coiled with ties." If you coil them properly, and I don't know if there is a name for the technique (coil, wrap, pull a bight thru, daisy chain then finish by tucking the tail thru), there isn't any need to add ties.
