Is shadow drag useless as people can type "vis" while sleeping to step out of the shadows?

If shadow drag is fairly useless, is it needed to get the only binder edge "Master Kidnapper"? (only edge listed in the thieves edge helpfile, I don't know if there's secret ones or anything.)

Does nimble fingers affect how often garrotte will succeed? And does the mace skill affect how well a blackjack works for knocking someone out?

Also, I wouldn't mind any tips and tricks you guys have for binders, as I'm considering playing one.

Thanks in advance ^ ^

would improved hide allow you to bind someone while still in the shadows?
