I use the Millenniums for adjustability. I actually own 4, although I really use only 2 at a time, although I did have all 4 installed at once. Two are set up for the bow for spider rigging while the 2 on the stern are raised up and setup for longline/crankbait pulling. If for some reason that I have only 2 sets installed, it isn't a problem to adjust them to the other setup should I need to change my method and fishing style.
If I'm not at work or taking kids to their activities, you might find me on "The Rez" fishing. If not there, I could be in the garage working on my boat.
