I have seen in post here on the p10's using your method of 20/20 and 30/30 in your area of trolling, but those who use them have had good success with them and I am not sure just what depth they are running. I am sure those that are using them will be on here and will let you know. Jul's and other charters here have posted using them please read earlier post. Please don't use those
suggestion for p10's and apply to dhj12's as they have a totally different dive curve and most without inline wts.
