First I would suggest switching to a minimum of 200lb. braid instesd of 130 lb. mono. In a following sea a 24 will not have any trouble breaking the mono. As sar as the depth that the planer will run, usually a #24 Old Salty on 100 ft. of 200 to 300 lb/ braid will run around 30 to 35 ft. I have intentionally left my planer out when trolling near the shaols to see where I start noticing the planer line jumping. It usually starts between 30 and 35 ft. depending on the seas. So I guess that on 100 ft. of braid it comes up to a little less than 1/3 depth per length or around 30 %.
