One problem that we had with extrusion was our chains becoming slack, although it was much easier that in previous years to fix because of the slots. One thing that we are planning on doing for Cal Games is making a block that bolts into the 80/20, and has a screw running parallel to the 80/20 that can push up against the pillow plock to tension the chain. After a whole season, we have noticed loosening of bolts and stuff, but its really nothing regular maintenance wont solve.
