Climbing Image NEB with Hartree Fock

[gg33]

I've been using IB3ION =3 and POTIM =0.1 for CI-NEB B3LYP calculations with EDIFFG= -0.05.

Which optimizer is recommended for a climbing image NEB run with hartree fock?

I don't expect any significant dependence between the NEB optimizer and the level of the electronic structure calculation.
