I love spider rigging 6 poles for Crappie, but being honest when I started two was almost too much most days. If I thought I'd be more effective I could move to 8 now, but I'd miss to many bites. Some of the other board members that I fish with always wonder why I catch more. Same water and same bait. I don't get more bites, I just don't miss many fish.

Don't over think it, get a kayak. Get on the water and pay attention to the fish and enjoy it! I went out last month for half a day and didn't catch a single fish. The first time that has happen in years. I had a wonderful time, the not catching didn't matter in the slightest.
