Either will work fine. They use to be the same company and then they split up for some reason. One is slightly different then the other but they both work great. I always used L&A but I bought a raptor with a extream in it but sold it to 1stwarrior.
Wel I was looking at it and some of the springs were facing different ways. Like big side and lil side. One of the bearings fell out so I was swapping them to all face one way and then when I was pullin one out the springs hot out I it and I lost a spring.
