I have a comp with a tower and you are correct this boat has a unique line of its own. If you install the tower I would make sure to honor its lines. Although the Indy tower is a great option you won't get the money you spend on it back. At least around Chicago there a several comps being listed for a premium! Hope they all sell, so I can get good value out of mine when I finally upgrade to a larger boat.
