This may not be what you were looking for, but I have an O72 carpet loop with 5 straights each side; down for 7 months. The pins are pretty loose on a lot of the sections. So much so that I bought the “tinmans” track pliers. Which of course solved the problem. I also had a dead short in a section due to the crimp machine pressing through the insulating paper. So had to check continuity on all sections. Should be normal practice anyway, I just didn’t know any better. All the sections had a machinery processing film on it, that I just cleaned off with alcohol. Seems heavy compared to FasTrak, but I have no other comparison. Once down however, I have had no problems with it. Hope this helps.
