Well, my skill level is, shall we say, is far from laser level (bought a laser level recently for a project, don't know how I have done without one all these years), more like Grand Pa's wooden level from the 1930's. You know the one with a single, very questionable, nearly impossible to read spirit tube.
A lot of places I ride have gravel and sand. On the shoulders of the road, intersections, parking lots, etc. This is the (high) desert after all, and that is what most deserts are made of. I find that if I need to slow or stop quickly from slow speeds on *** puckering surfaces the rear brake gives me a bit of a margin of error. Also in slow speed maneuvers, dragging the rear brake seems to work better (for me).
