I have the largest size Wald baskets front and rear. If I try to put heavy loads in front, yes, steering is affected substantially.
SO!
When I get a load of groceries, I separate the load out between heavy, dense objects and lighter, bulky things. My bottled water? I break up the case and put it in the back baskets, along with the canned goods, milk, and jars. That leaves me with a few bags of things like chips, vegetables, bread, and the like; those go up front.
