All the forums and reviews I've read point to the Kodiak brakes being the best. I even found a series of youtube installation videos. etrailer has a set, but once I save up enough, I'm going with amazon.com because they come with bearings.

I'm also going to go with the CTS Hydrastar actuator because it's compatible with my Ford OEM brake controller.

If anyone has any issues with these, please let me know. I'd like to have as many pros and cons as possible.
The reason I'm asking about routing is I have this fear of the lines getting damaged by a rock or something and losing the brakes when I need them.
