Re: Can I use a differently shaped mast?
The strength of a section lies in the location of material, not (necessarily) the weight. Case in point, my company supplies, among other things, two sizes of aluminum rafters. A 6" capable of spanning 18 feet and a 9" with a 24' span rating. Both with the same amount of aluminum per foot. That said, I'd bet these section are virtually identical, weight wise. Long story to say, "You're fine. You wouldn't notice the difference even if there was one."
