It is all about the fun of it -- a 5 pound catfish would be a wonderful fight and that is about what would go chasing a little bitty buzzy thing tossed out into the water.
Bigger is just better ..... and if the line pops, so what?
MM's gonna haul one in and fillet it, and that will feed all of us anyway.
I have heavier stuff, and can get it out if needed.
Me, sitting in a folding aluminum chair, keeping tension on the come-along until the catfish gets bored and simply doesn't see the net coming up from the bottom.
Or me, holding the reel half of a broken ultra lite rig ...... could happen, as the line is over twice as strong as was ever intended to be used in that sort of wispy spinning rig.
