I think it was the initial stability margin after removing those simulated fins. It was only about 0.5 (minimum required margin is anything over 1.0), and I was looking for a way to increase the margin without adding ballast. Ballast is adding mass, and I was trying to keep from doing that. It still took some...
But your version came out better than mine, even with the additional mass added. And you're right, the longer tubes do look more appropriate, more proportional. I just have this "thing" against adding dead weight to a model if I can avoid it...
