Keep in mind the wax takes an enormous amount of energy for the bees to produce - there's a reason why so many beekeepers use conventional Langstroth hives. The top bars are fine, I'm not against them, I just wouldn't run with them. A friend of mine has one as an experiment, he doesn't think it'll make it through the winter, though, it's very weak - not because it's top bar, the bees just didn't do well for him this summer.
