Are you kidding? Towers are not only possible with a 20, they are seen quite often down here in Florida. I have even seen towers on 18's. The question is, why would you put one on. If you fish calm or shallow water they are more appropriate than if you fish offshore water. Spotting tarpon or other gamefish is much easier. The downside: towers add 200lbs not including one or 2 fisherman. They also raise the center of gravity and increase your moment of roll.
