Vary the amount of line you have out on your cranks. I may run 50 feet on one rod and the one beside it have 120 feet out. Lots of times if you get in a situation where you are forced to make a reasonably tight turn, speed up your motor till you complete the turn. I run my Terrova on "rabbit" lots of times if it looks like the lines are going to get together in a turn.

It is also advisable to reel in a couple of your baits every few minutes to check for tangles. Lots of times it is very hard to detect your cranks being tangled up. You are fishing dead water if the baits aren't separate and running true.
