I would suggest you start with MILD, Enz, since it incorporates many of the things you will need to do the other techniques... which is a good thing, because there really are no "good" or "bad" techniques, and as you become more experienced you will likely find yourself choosing techniques because they are convenient to you, and not because they work better than others; lucidity is all about mindset, and not techniques.

I also humbly suggest that you look at my Lucid Dreaming Fundamentals thread, which tends to illustrate that, in the end, techniques don't matter.

Good luck!
