While pike hang to the bottom, they look up, and can see a long ways. The 3' I quoted earlier might be a little deep. I like 3'-5' for my deepest rig. Here is a very useful quote about pike, "It is impossible to put a bait too high for a pike, yet it is very easy to put it too far down" -Infisherman. I've been noticing this recently, especially along sharp breaks. Pike might be roaming in 3' for all I know, and look for food off the edge. I'll set a bait 12' down in 15' of water, and get nothing for hours. I'll move it up to about 8' down, and I'll get hit in 5 minutes. Start at least 3' off the bottom, and make your adjustments. With more people, just put each tip up at a different depth.
