I dont use any baitrunners, but for all my livebaiting, especially larger baits, I set my reels on low drag, just enough so it wont click away as I drift. Sometimes I put it up a few more clicks from there.
Having a pre-set drag upon strike is a nice feature on baitrunners. Saves the guess work out of how much drag to apply.
The DL's are built tough and solid, with higher drag and a larger choice of different sized spools.
Downside is, they are heavy and bulky. If you fish only with bait then they are an excellent choice. But if you end up fishing with lures as well.. I suggest a non-baitrunner. As they are lighter, smaller and stronger overall.
Just back your drag off and its pretty much the same as a baitrunner, except you just gotta increase the drag upon strike.
