yakjammer......I suspect as you mentioned, the longer PA-14 might track better.....keep in mind that my 2013 PA-14 does not have the "tracking skeg".
Yes, I do fish the Columbia River occasionally, but most often, I fish Lost Lake. It's located a few, short miles north of Mount Hood and the beauty is breath taking.
I down rig fish in the 25' to 110' depths, trolling a 4"-5" quickfish style lure and some larger spinners. My weight is 4.25 pounds and I use a Cannon electric downrigger.
Regardless if I catch a fish or two or nothing at all, I get a really good workout in the best setting I can think of. I also release all fish that are under 18" in length.
