Me and my 8 year old son were at the lake the other day bass fishing and the was a guy trolling around the middle of the lake with several poles on a spider rig. My son told me he wants to try fishing like that cause it looks realy easy. So i made a couple rod holders and a double seat for the front of my boat,then i realize i dont know anything about crappie fishing. Like what size rods work best,how fast to troll, jig size and color? Can anyone shed some light on this subject for me?

I've spider rigged a couple times but I'm certainly no pro at it. When I have done it we used 10 or 12 foot light action rods, with 2 hook crappie rigs on them. Head-hook a live minnow on each hook, drop it to where the bottom hook is about a foot off the bottom and repeat. There have been times when we have gone for hours without a bite but others (Reelfoot Lake!!!) where we have had 2 fish each on 3 or 4 poles at a time...If you are fishing for meat this is the way to go, if you're in it for the sport, not so much
