SB, you are "jigging" for fish. That is not my prefered way of fishing but then I rarely have access to deep water lakes. Tight lining is when you put enough weight on to keep the line vertical while drifting or slowly trolling around. In my opinion that is much better as you can cover a lot more area. Once you find them, you can keep going over that area or I believe some people will anchor over that area. I'm sure some of the more experienced people that use this method will jump in here and tell you how to tightline.
