On paper, some of these teams seem underpowered to me. Bueno and Nicolas do not equal RonRon and Manu. Juice and Arta do not equal Anderluck and Bradley.
Of course any given point can go any way and Jai-Alai is hard to predict. So there is no way of knowing how these teams will actually perform.
Still, I would take RonRon and Manu or Douglas and Manny over Bueno and Nicolas any day of the week. And I am a huge Nicolas fan.
