Glenn - Now's the time to use your experience, think about the tanks you like the look of, and do the envisioning of what you want to end up with - a rock wall, or a more open look with 2 "towers", an open area in the middle, etc. etc. etc., plus what corals and rock you may move in from the 130D. Later on it will be much more difficult to change things. Just because you have all that rock doesn't mean you have to sacrifice what you want - pull some out if it's best to fulfill the vision you have!
