If you are confused about a big decision, you need to get more information -- it's as simple as that. It takes the sun to burn off the fog, and it takes details to make the picture you're looking at clearer. So do whatever you have to in order to better understand the options ahead of you. Ask the right questions of all the right people. Make a chart. Use color coding. Sort things alphabetically. Do whatever it takes to know this thing inside out.
