V. Depending what you mount in the canopy and the material that you use. If you only have couple MH setup and T5s, I don't really think it's that heavy. Use a thicker/heavier material for the sides and the frame would help holding the canopy down when you lift the top. Maybe best to move the top hinge toward the front a little bit but not in the middle. That will give you a lot of room to work on the tank.
