The nature of aluminum is such that it's less flexible than steel. For this reason, and its light weight, it is why it makes a good choice for a certain type(s) of bikes. Less flex in the bottom bracket when proj'ing hard. However, this stiffness comes at a cost: comfort.
So since I figure dopey is not looking to do a sprint like the Lion King, I figured I'd drop the comfort aspect of frame material on him. FWIW, I rode a Trek AL frame for years. The reason being, I'm a big guy, and I'd loose mucho energy when I'd stand up and nail it due to bottom bracket flex.
