As best I can tell the differences between them is that the Pro tower is shorter (only when folded?) and has the side surf pylons. Are there any other differences? It seems unworthy of the cost differential. Just how much shorter is the Pro tower? The sales guy at the local dealership indicated that the Pro tower might be easier to fold but as far as I can tell they seem the same from that perspective. This is a concern as we have some low bridges that I'd need to fold the tower to get under.
