Caster's tech is about as strong, if not slightly stronger, than a thrown Gae Bulg, and that penetrated Rho Aias, in the UBW series.

Yeah. And that was a copy made by EMIYA, who can only make imperfect copies (also, it didn't penetrate the last layer) Against the real Rho Ais, or it's prototype Phantasm, Gae Bolg wouldn't have come close.
