I live in Victoria, Australia where it's currently heading into winter. I want to do my TDI advanced nitrox, deco procedures and potentially extended range. Since the weather can be pretty fickle here I have been thinking about doing the courses overseas where the diving is easier and the weather is more reliable.

I know I can do advanced nitrox and deco proecedures together but does anyone have opinions about following those two up with extended range as soon as possible? I figure if I can do one trip that would be ideal.
