I don't have any skids besides the factory one, and so far I really haven't needed them. And I do some pretty good trails. I just position the wheels so that if something is going to get hit it's going to be the sliders and nothing else. If I were to end up getting skids then I'd have to move back up to 700's. But with the weight I'm carrying now the 650's seem to be just right.Interesting to see you switch back to 650lb springs. I just added a brute force fab bumper. I've not added a winch yet but I do have skid row skids. Despite the weight my ICON coilovers with 650lb springs are doing ok. I was worried it would ride really rough with the bumper.
