We just bought two Shimano Spirex 1000RE's to hang off of our 9' Jigging rods. Prior to that we were using (and still use them on our backup rods) Shimano Spirex 2000RD's. They also double as our walleye reels when in Canada. The 2000's are a bit big for crappie fishing, but work ok. They just waste a lot of line on the spool.
Hope that helps....
