I figured that I have the time/money to build it right the first time, so might as well put some money in the correct places. Will a 30/8.8 work? Yes it will, I had that same combo in my YJ(although they weren't locked). I tend to overbuild all of my projects so D44s were the natural first choice for me. And in the future, I can go bigger if I wanted without having to change much.
