>>10691075It's so baffling to me every time I've heard the Rg Zeta talked about, I've built three versions of it and never had a single problem. It's easy one of the best rgs, and looks absolutely fantastic.

>>10685591The Casval version is probably my favorite version of it. Weak shoulder balls aside the kit holds up great. The zaku II is super solid as well.
The only rg I didn't really like was the Sinanju, the joints are super unstable and the waist and shoulder joints are a joke.
The best rg is probably the Nu or Crossbone, they are great.
