Climb it the easiest way. The lines drawn on photo-topos aren't intended to be super-accurate; between the topo, the description and looking at it yourself you should be able to work out where it goes.
In general it's probably safer, more secure, but strenuous to swing along a break with bad footholds, and it's scarier to teeter along with bad handholds. So most traverse lines are usually done with hands rather than feet following the obvious feature.
