"Pushers" around here use lengths varying from 7' to 20' ... or whatever it takes to insure a couple of feet of separation between rod tips. I've used 7' Bass rods & 14' collapsible rods pulling cranks, and that's with 2oz of lead on the braid line (and 5' leader of 6lb test mono). Line counter reels were on all poles ... boat speed was generally around 1.8mph ... and crank was let out around 40ft (give or take 10ft) to run around the 12-15ft depths.

I was always using someone else's equipment, and fishing from the back of their boat, as the longest rods I own are only 10' in length. But, their system worked, as we caught fish on every trip.

They use the same long poles (14'-20') to push jigs or jig/minnow, and just switch out reels from the counters to spinning or baitcast & mono line when spider rigging at slower speeds.
