All lines will stretch except for Q-power so if you are concerned about that you might as well get the $67 lines. I've had a switch bar for two years and the lines stretched but within the limits that I can compensate for it at the bar. They have lasted extremely well. They look a lot like the Naish lines that I had before which also lasted a really long time.

I used to pretty much like all the lines that most companies supplied.
Ocean Rodeo used to have good linesets.
The white Slingshot linesets used to be really fine.
I like the Ozone linesets.
But all the companies that went to the white lines with the colored flecks, in the last three years, they are all sh!te.
