Pushing Crankbaits

[Skippa Chippa]

This is going to be new to me, I may make a mistake so help me. I usually pull with 6 poles now I want to get 2 more baits in the water by adding 2 more poles. My set up is 2- 6' out the back 2- 7' poles on an angle then 2-10' poles at 90* out the side of the boat. The 2 I want to add will be forward the 10 ftr, 2 more 6' poles and I want to add a weight "like pushing" to keep the bait close to the boat. My question is how much weight and line to put out say I wanted to keep the bait around 12'. My average speed is 1.5 to 1.8 mph. I will be pulling C55s, C33s, Arkies, Bandits and Picos about 3-4' behind the weight. I sure appreciate any help, Thanks in advance.
