I do the batch sparge with a bag setup. I have a ~1' SS braid at the bottom of mine that goes to a bulkhead/ball valve. Honestly, it's probably not necessary as the bag filters better than the braid does but it does seem to help with efficiently running the wort out of the cooler.
One option I've heard is to just pull the bag back away from the outlet hole slightly (tie it off with a bungie or something) so that it doesn't clog. I've also heard of just jamming a SS spoon down near the outlet hole so the bag doesn't get pulled in during run off. A bazooka screen would work too. The one think I caution when using a braid or screen is to watch for sharp metal edges if you cut your own SS braid - they can rip your bag pretty good if you aren't careful.
Ultimately, whatever you use (or don't), it won't change your resultant beer one bit - you should choose whatever solution is the least pain in your neck (and I hear you about not wanting to hoist the bag - I refuse to do that).
