and think it`s really a sharp, inexpensive solution. i`ve also seen metal grate run from hillsides to buildings ( unsupported or every so often ) and feel the cost/wear ratio, depending on you`re taste and local comperables, isn`t going to be worth it. the pavers really impressed me as a high quality enduring item. i want to try it first chance i get. that`s all i know and good luck.
