Seismic's Rock!,  Friday, 03 August 2007 I have the 45 degree trucks in the front and back. These trucks are phenomenally great, when they work. I have had the problem of them not going straight. I have heavy springs on them, because i'm a big guy ;p when i ride them though, i have to lean to the right to keep them straight. I tried over and over again to re-tension the springs, but they still want to veer off. When they do work though, HUGE traction, great turning, and great stability. I honestly would never want any other trucks since i got these.
