The aluminum ones are much more precise when coupled with a good servo. But your right about the replacement usually being much better than the original. They were really bad on the Volcano a while back [&o]
LOL and yes 2 of my customers converted to the aluminum and liked them very much (forget where I'm at sometimes [&:] )
One of the first upgrades I recommend in all the models I sell, only things higher on the list is TX, RX and servos
