Channel Cats are not important if you want heavy bass.

Many would say they are detrimental to that heavy bass goal.

I'd leave them just for some variety. In a 19 acre lake, I'd probably add some every now and then just to sustain a small, very small, population.

Excerpt from Robert Crais' "The Monkey's Raincoat:"
"She took another microscopic bite of her sandwich, then pushed it away. Maybe she absorbed nutrients from her surroundings."
