I have usually waited to buy the long lines at the Nationals so I get them without the extra, needed bend for shipping.
At the Nationals it seems that the more knowledgeable people of years ago are being replaced by less knowledgeable people.

Also, wasn't there some relationship between FineLines and Right Stuff? I recall that one did the tube bending for the other.

I have always bought the OE material instead of the Stainless. I had heard that the hardness of the stainless created issues sometimes with getting a good seal at connections. Also, I thought, if the crappy originals lasted 35 years and 80,000 miles, surely the new ones will last longer when it is stored in a climate controlled garage and driven 1500 miles a year.
