Hydrox has factors, OTHER than flammability, that limit its use. Somewhere I have an email discussion about that very subject but I do not recall the content. I *think* Hydrox has depth limits due to it being more difficult to breathe than helium based mixes (but don't quote me). By and large there is no good reason to NOT use helium as either Heliox or trimix.
