I will say that single arm laterals are way better than bilateral.
Of course your body angle changes how it hits, lean left and the start is harder.
When doing cable pulley laterals you can achieve the same effect by having the pulley wheel about the height of your hand. If the wheel is at ground level you can change the lresistance curve simply by stepping further out. Say you do front cable raises and hit failure, take a big step forward and you can get a rep or two more.
