Yes I was originally adding material plus disabling back-face culling per stateset per Geode, hence the huge saving.
Moving the colour to the vertices (one colour bound overall) does the same job as far as I'm concerned and definitely saves on memory/performance :) I'm still having a lot of issues with memory - probably due to the way I've constructed my scenegraph - I will elaborate next week on the other thread you quoted.
