You know if you put your kayak in a
lake once in a while you could have been trolling with that too
Some guys even use downriggers
OK, I'm done being a smart ass for this post
I saw some guys in a small boat doing what Don described at Speedwell Forge a month or two ago. They were using a standard red and white round bobber. I didn't see them catch anything, but Speedwell can be a tough place.
If you have electronics to find the depth the fish are at you know how deep to troll. Otherwise just try letting your bait down a little at a time until you start getting bites.
Lead core is usually a
DEEP lake thing. I hear guys talk about it on the Great Lakes, and really big reservoirs in the south and west. Here in PA I am not sure anyplace is deep enough to need that, or to really get the benefits of it.
