It's awesome that your failure happened while you were sitting still. Good thing that you found it then instead of in an emergency situation!
I'm using SS lines from Technafit on Q2.

They have a plastic coating over the braided cover, so that should eliminate the dirt issues. One of the collars near the fitting cracked and they replaced it at no charge... and this was well over a year after I bought them. They're very easy to deal with and customer friendly. I would highly recommend them.
If I can anticipate someone's next question... I didn't drive Q2 much at all before I did the major suspension and brake overhaul, so I didn't really get a good comparison of the differences between these and OEM. The brake feel between Q1 and Q2 has always been very different for some reason.
