I don't see any reason to move on to another technique after you succeed in getting lucid with one. If you became lucid once with that technique, you would probably want to keep practicing it in order to improve it. I suggest that you try one technique over a month's time. If you get very little success by the end of that month, then you should move on to another technique. Then you should experiment with that technique for a month.

Since you seem interested in awareness you may want to read this tutorial if you haven't already. http://www.dreamviews.com/f49/all-da...gyoshi-113253/ It's a very good way to practice DILD in my opinion.
