To provide an actual response: the Rope walk style currently causes the enemy to dash at Link with a speed of Step + 100.
Whether or not this ought to change to something like Step * 3 is an interesting question. I guess one of the reasons why I went with the former is because you could give an enemy a Step of 0 and then it would nonetheless charge at Link when Link crossed their line of sight. And also, that slower enemies (with a step of 25 or something) would charge Link with a slightly peppy 125 Step instead of a not-quite-so-considerable 75. Admittedly, it means that enemies with a Step of 125 only dash at 225 instead of 375, but to be honest I find Step speeds above 150 to be kind of unpleasant to deal with as Link and more revealing of the artificial limitations of the NES movement styles, so the current system means that really fast enemies' dashes are kept a bit closer to the bounds of reason.
EDIT: Hmm, but I'm reminded of the fact that Armos uses the Walk Attr. value to determine its alternative speed. I guess that could be utilised by the Rope too?
