Q: what is the working load limit for this 1/4 in. galvanized cable?
A: The breaking strength of the rope is 7000 lbs. In order to figure out the working load limit, you divide 7,000 lbs by the design factor you put into the system. For over head lifting, generally the design factor is 5:1. In this case, you would divide 7000 by 5 to get 1400 lbs. If you are using wire rope clips, that working load limit is reduced by 20%. Other terminations have lower or higher termination efficiency. If you use a 5:1 design factor, you will get the most life out of your rope, and increase safety for your project.

Q: Is 7x19 cable better for bending around pulleys than 7x7?
A: Yes, 7x19 cable is more flexible than 7x7 because it is made from more smaller wires that allow for easier bending. Read more about cable construction here http://www.e-rigging.com/cable#Cable_Construction_Guide
