It is quite THIC, it could also be that significant weight savings come at the cost of ease of manufacture at least in the case of the RS series engines. It does seem like it should be lighter, but that ablative nozzle is a solid brick of resin and other shit while a regeneratively cooled nozzle is quite thin walled and mostly made up of empty space.
It would be interesting to know if the RS-68's TWR spikes substantially as it burns through more layers of that nozzle.

I'll just repost my question since no one answered it before the previous thread died.

Anyone know a database of ablators that can be used in rocket engines? In particular the erosion constants of those ablators.
