I wish I would have known that Logstor was that flexible. I had to replace my line about 8 years ago. CB used a 2 line system in a 6" dia. insulated Styrofoam tube. It did not have a oxygen barrier and the pex turned into a line that was as brittle as glass. I installed the line in a 7" sewer pipe in case I would have to replace it, that was a good decision. Dealer came with the new line similar to Logstor but not very flexible. I didn't have a choice at the time, I got it for the cost of the new line minus the cost of the old line. Dealer brought it on a trailer with a 15' dia. coil. Unrolled out it wanted to curl back up. It is a good pex line and well insulated but you can't bend a 8' piece. Just wish I would have know about Logstor.
