Should I chose one brand over the other? I like the CS ones a bit more since they are covered in plastic. Anyone have experience with either?

 

I'm using the Mazdatrix lines. They fit just fine.

With brake lines, IMO it's not that big of a deal with the coatings. People have said dirt can get in the weaving of the lines and cause problems, but I've never seen it happen (and I talked to several engineering friends who say the theory is sound, but reality it just doesn't cause a problem).

The other thing to worry about with SS lines (of any sort) would be them rubbing on something as it would act like a saw without some coating. The brake lines have mounting points so that's not a problem either.

 

I'd definitely be more worried about the lines rubbing on something than the dirt.

I got a tip from a friend with a lot of experience using stainless steel braided lines.
He said if it's rubbing on anything wrap a tight layer of electrictal tape, than over the tight layer wrap it loosely, than wrap another tight layer on top of the previous two, and it should be protect against rubbing on something sharp.

This came from a retired Navy vet who used to do this to braided lines on an aircraft carrier.

By the way I am running Goodridge lines, got them for 80 shipped.

 

Where can I get Goodridge for 80 shipped?
