I'll tell you this ... if I don't watch my line, when I'm casting or dock shooting jigs for Crappie (which is what I most often do), then I'm probably gonna come home pretty much empty handed, a majority of the time.
When Bass fishing with plastics (ie "worm fishing"), day or night, I still watch the line, because I've seen too many times when I've looked away or got distracted ... and start to move the bait, only to have the fish swimming off with it or drop it. You can't always depend on "feeling" the bite, but if you can see your line, you'll rarely miss seeing even a light hit. That holds especially true when fishing with blacklights. I've fished three out of a boat, worm fishing at night under blacklights, sitting in the front of the boat ... and still saw hits on the other two lines, outta the corner of my eye !!
If there's anyway I can accomplish it, I prefer to "see" a hit, as opposed to feeling one ... for the simple reason of lessening the possibility of the fish feeling the rod resistance. That goes for both species of fish, Crappie or Bass ... as they'll both blow a bait in a heartbeat, if they feel much resistance ... especially if they're spooky, heavily pressured, or if they're not really hungry (but, just can't resist the temptation).

You go playing "feely mouth" with a Bass (waiting for the tap, tap ... then lifting the rod tip to see if he's still there) ... you're gonna miss alot of fish. But, laying a hookset on one, a half second after you see the line move/jump or go slack a little sooner than it should ... you're going to have a very surprised fish on the end of your line ... LOL !!
