The Athena was not terrible to add, but I did have some issues with one side having sticky guide rods. I did get them replaced no questions asked by Rep, however, and they worked better afterwards. The trolleys are fine, but they don't have any rollers. They're not as smooth as others, but I haven't had an issue adjusting with one hand. For plate loaded FTs, it's fine, but if you can afford it at once, just get the selectorized one.
