I am looking to fine tune my long lining. If I am looking to long line two jigs one 1/8 and one 1/16 on 10 pound line. Clear water and the crappie are suspended only 2 to 3 foot down. So I am wanting to get the jigs a good piece AT LEAST 50 FEET from the boat. So what would be a good speed to make these jigs run 2 to 3 foot deep with 50 feet of line out?
