Paul, is the RB part a comparable product. A casting versus billet
CNC with what looks like a replaceable insert.

No but the RB housings works on the TTC. And they are lighter.

IMHO cast iron is not the best. The best would be 4130 Heat Treated
and hard chrome plated.

Hi Paul,
I spoke to Promaz a few hours ago and they are working on aluminum rear housings now and expect the first next week. They are planning center housings next and expect the whole set in about 3 months. The large 20B center housing is scheduled for production later in the year. The cast iron insert is hardened but Promaz did not say what hardening process is used.
Maybe if we made our own 4130 insert, Promaz would install it. I can ask later when they sort out their present engineering plans.
