I have a 6' medium light Berkley cherrywood rod I was considering using for crappie fishing. I am going to spool it with 4lb line. I would be using jigs and minnows of course. Do you more experienced crappie fishermen and fisherwomen think this world work

Eye-less cane poles were/are being used to catch tons of crappie; 50 years ago and today. The set up you describe is just fine. The crappie won't mind a bit. Once you really get "into" crappie fishing, you might want to expand your arsenal a bit, depending on your budget of course. Take a look at the 7' B n' M Sam's Super Sensitive rods. Going for about $50.00, this rod is very sensitive and makes jig casting very easy. A light spinning reel under this rod, with 4# test mono will do you just fine.

I think your present combo would be fine for crappie and other panfish. Catching fish on 4# line is lots of fun.
