I have seen them come to the ridge and the bench, it's hard to predict. If there is a saddle, as Jim said, that is killing ground. Look for the end of a bench coming up to the ridge top or good crossover points, these are good set ups. An old gobbler likes a view, but he also likes a quick get away. I have watched a lot of them stay just over a crest then pop up right on you. If your hunting a bench set up so you have a sight line down the lip of the bench, more times than not they will travel the edge so they have a quick exit. . Look for deer trails and old roads as a key. An old gobbler is as lazy as the man huunting him, he'll walk the easiest path to where he wants to go. So I have no rules about ridge tops. If it is a well traveled ridge top I will go down to the bench, because they will associate the ridge with danger. Oh I forgot that would be pressure and that's a myth.
