It's more difficult to maintain heat and humidity in glass with a screen top than plastic tub... With a glass tank, you'll most likely need a heat lamp in addition to the heat pad. And then depending on where you live, you might need to think of ways to increase humidity, since a heat lamp with drain humidity from the air. Anything a tank can do, a tub can do better... I personally don't think it's weird at all- whatever works the best is the best to me, especially if you have to transport often.
But if you really care about the aesthetic, it's not like it won't work. Here's the glass tank guide: http://ball-pythons.net/forums/showt...-With-Pictures!
