Len: THere was a nice article about crappie fishing on Diamond in the Kazoo Gazette. Guy catches a lot of crappie there - he and writer of article caught over 50 crappie on two seperate days.
Using 2lb test with 1/32 oz jig under a bobber. Letting bobbers drift over weeds about 6-8 feet down. Jig was suspended just over weeds.
Guy with 6 lbs line caught nothing until he changed to 2lb test.
