Contrary to most posts I would personally do LTU first if you are unsure. Not to put you off from buying AM, but I have quite often thought that doing LTU for 3-6 months first would have helped me enjoy the run much more. Don't get me wrong I still get the results, but lets say the moulding of the clay is much rougher. Go with what you feel like is the right step for you to take right now, you won't have the same results as everyone does anyway.
