So if I understand correctly …

Hydra (monometal) → FiRROX (bi-metal) → TiRROX/TiSSOX (titanium)  
Steel (bi-metal) → iCEBERG (hybrid) → TiTANIC (titanium)

Am I missing any from either tree branch here? The Hydra branch seems to be missing plastic and hybrid versions, while the Steel branch is missing plastic and monometal versions. Is this correct? Or are there models (older ones perhaps) belonging to either branch that I’m not aware of?

The Shooting Star is pretty much a full plastic Iceberg.

Ah, right you are. _Much_ wider, of course, but they do refer to it exactly as you say.
