| From my little understanding, the main skills would have been taught on your adv nx/deco course and most of the rest is theory. Like you I have just passed the adv/deco and my plan is to spend a couple of seasons practicing the skills and then, when I feel competent, go straight for the trimix for times I want to dive below 40. This is probably where the DIR boys have it right, seperate the fundemental skills into a course unto itself. After finishing my deco I was told by my instructor he was happy with my skills and would have no trouble if I did my trimix, but then at £700 he would. So I will wait but skip extended range as I have no intentions going to deep without trimix.
Good luck
