Looking to replace a PSU with the Seasonic S12-430 but noticed they 12v line is split into 2 sets. Are there any Recommendations on how to split my components between these two sets of 12v lines?

You have no choice in the matter. One of the 12V lines is dedicated to the 4-pin "CPU" connector. The other 12V line goes to everything else, including ATX connector, all 4-pin molexes, etc. That is per the ATX 12V 2.0 specification.

Yep no choice but it's really a logical split for usage and should add stability in general as well.

So which 12V line goes to the CPU 4-pin connector?

If it follows the ATX 2.0 spec, the +12V2 rail goes to the CPU 4-pin connector. From looking at the manual ftom the Enermax Noisetaker 2.0 I bought yesterday, the +12V2 rail also goes to the big 20/24 pin plug. +12V1 goes to everything else (hard drive connectors, PCI-E graphics card connector, etc.)
