I am a bit confused. I was under the impression the AST 4200 were similar in spec to the JRZ RS, not the RS1. The AST 4200 and JRZ RS are double adjustable. The RS1 is single adjustable.

What are the main differences between the RS and RS1 in terms of on-track performance and off-track usability?

I am planning to upgrade at some point in the future so I am interested.
