While perusing the lures at Wally World this evening (after getting my lins.), a good looking woman ask my opinion of what one line would serve best for catching crappie, bass, and catfish.
I honestly hadn't thought about it and didn't have a pat answer for her. I had thoughts for each species, but not for an overall line. I made a guess: 17-20 mono.
Thing is, after extensive conversation, I became pretty dang certian she was flirting with me and, in addition, there's also a good chance I'll run into her again. I want to be informed the next time I see her.

So, what's a good "overall" line for catching multi-species of freshwater fish?
Thanks
