I thought I would put my 2 cents in
I dont troll for skis as much as I cast but I still manage to get 30
or more fish trolling every year.
I have to say that I find running depth very important and I do spend most of my time running my baits fairly deep.
When I say deep I am talking 15-20 ft down. While I always seem to have a bait or 2 up higher in the water the ones that are running deepeer are the one that are more consitant.
I like to have them making contact with the bottom on and off and most of the strikes come when the bait clears the bottom ( breakline ).
I run many differnt baits and use inline weights to get some baits down. Some of my favorites are Ernies, jakes, grandmas, depth raiders, believers, swimwiz, triple d’s, deep invaders, bulldogs
Ill run just about anything in the prop wash also
As far as equipment I dont use heavy rods or heavy line. Med heavy 9′ with good line counters 30lb power pro a good leader. I set my drag as lite as I can with out the bait taking line while trolling I also set my clicker so it sounds the alarm when a fish hits or the bait snags up. In open water its not about powering a fish to the boat long lite rods will beat a fish faster than you think.
Hope the info helps
