VPI Scout 2 JMW10 vs VPI Scoutmaster 2 w / JMW9

Which way would one go if tracing error is to be mitigate to non-audible levels? The beefier Scoutmaster 2, or the Scout 2 JMW10 (classic arm, non-3d printed)?

I will say that I have a Rogue Atlas Magnum amp with a Conrad Johnson pre - so it's not like I'm going to be rumbling my house with some solid state horsepower.

What are people's opinions out there?
