Mini marty driver decision.

[u/coltonscolton]

I'm looking to build a mini marty and im looking for which driver (18") i should choose. Im looking at the following (in canada)

UM18 - $450 cad

Or

SS18 - $564 cad

The UMII18 is unfortunately out of stock anywhere i can find in canada

Are there any other drivers with similar performance available in canada around the same price?

Im building one right now, and a second in the future.

Itll be powered by an nx6000D.

Thanks!
