I'm planning on running quarter inch line on mine just because I've had some systems it before that were all 3/16 and you could almost feel the Restriction in the lines as you push the brake pedal down. Myself personally I just didn't care for it.

I really don't know why they would recommend against using larger line. On a hydraulic system you get out whatever you put into it.
I hadn't thought about the restriction being less. That would be a plus. Someone told me that 1/4" tube would stretch more but this is really high quality tubing polished inside and out. I'm learning a lot about the importance of flow on an engine lately, why would brakes be any different.
