The best way to handle the combs is to turn them on their long axis so that the top bar is facing straight up and down. Then you can just spin it around to see both sides. Or you can just support the bottom of the comb with your fingers.
Yes, it's all cut comb with top bars. It's not really that big of a disadvantage. It makes it easier to cycle out old comb and you get a huge beeswax harvest, which is actually pretty good stuff to have. You can sell beeswax to herbalists and the like for upwards of $25/lb. Make it into candles, salves, lip balm, etc and the value added profit is pretty high. Or you can just make the stuff and give it away as gifts. Salves especially are super easy to make, if you want a recipe just let me know. Also I don't need an extractor. Just crush the comb in a colander and let the honey run into a bucket. Easy peasy!
From the stats I've seen top bar hives produce slightly less honey than a Langstroth, but 6 times as much beeswax. Also, a Langstroth setup costs several hundred dollars. It costs me $13 in lumber and screws to make a top bar hive. I wouldn't recommend top bar hives to commercial beekeepers, but for home hobbyists I think they can be good, and simple too. Personal preference in the end, I guess.
Going to help a friend to load up several dozen top bar hives that he's taking down south for the purple sage bloom. Moving hives kind of sucks...
