I may be the odd ball here because I don't like anything over 12 foot. If the fish are shallow they are usually around some kind of cover and I won't be spider rigging anyway. I spider rig with 10's and 12's when the fish are in 8 foot or deeper. Way to many hassles bringing in fish, storage in the boat and even storage when out of the boat with the longer rods. The 10's and 12's can stay together from the beginning of the season until the end when I am done for the year. I make my own rod sleeves to fit my spider rig poles and the don't tangle in the boat. This also helps me cut down on how many poles I keep in the boat because if I want to pull jigs I can use the same rods. I fish every method there is for Crappie at some point in the year and being efficient as possible is important.

Just wanted to give you another perspective on spider rigging.
