I've been changing my 160 x 600 skyscraper units around trying to see if I can increase clicks. I have been using them in the left column with a menu underneath. I've now tried putting the skyscraper unit in the right-hand column with a menu on the left hand column. I'm just wondering whether I should swap it around, the skyscraper in the left-hand column and the menu in the right column. What you guys reckon?
