Yes, that is all a comp cut is. It allows for more wheel travel, and gives the owner room to stretch the wheelbase slightly for better approach/departure angles as well as gives it a bit more stability. The disadvantage to doing a stretch is you often have to find other options for your fuel tank.
It just depends on what you want your rig to do, and how far you would be willing to cut it up to get there. I personally wouldnt go more than minor fender trimming, but that is just how I like mine to look. Your opinon/needs will vary.
