Have never tried longlining at night, it wouldn't be impossible but would be hard to keep everything going like in the daytime. You are always looking ahead to see what you need to do but in the dark this wouldn't be possible. You can always be the first to try it
I have spider rigged at night after setting up for a regular nightstalk and had already pulled in the bait. Done this quite a few times but never caught as many crappie as setting still.
