I would say the Fury is a excellent compliment to a Saint. The River is great as well, but the Fury and Saint feel nearly identical in the hand. As far as the River comparison, I would say they fly close to the same, the Fury for me just goes into it's high speed turn abruptly, as to where my Rivers flip slower if that makes sense.
