You missed the part where I stated I work for the shop..... also I completed extended range trimix cert in July. I have decided I am not taking advanced trimix until I am on CCR. I am already going to have to recert on the tech classes I currently have on ccr.
Just making sure you're clear that they are not just "crossovers." You have specific, agency-defined prerequisite hours in order to take MOD2 and MOD3. It's not like you can come in as a hypoxic trimix diver and jump straight into MOD3, you've gotta do all the hours first.
