Thanks Achim, Iterators are very strange beings indeed. In another comp I'm working on I have a Iterator > (Render In Image > Composition Importer) + Billboard, with the Iterator set to 1 iteration. This runs faster than if I have the contents outside of the iterator.
Just another thing to note down I suppose!
