I don't think there is any downside other than increased mass, but then again, we are talking abou brushless here. Increased mass near the front means more traction, which means you can put down more power.

Regardless, I guess this is a thing of what the ed user likes best. I like sealed better, some others might like open better for the weigt savings.

Any word on the distance between bearings on a standard center diff?

BTW: My gerbox is currently less than 200grams, and still has plenty of room to reduce that more. I am going to wait till I have final dimensions before I really lean it out though.
