I was considering doing Helitrox with my AN/DP course, that just made my mind up.
I only wish somebody would have told me sooner so I didn't make the mistake of not doing helitrox.
Even if you don't use it a ton, there will be a day/dive where you go, "well $hit, i wish i had trimix for this". It's frustrating when all your buddies are on trimix and you're 150' on air/25% praying there is no current.
