A Trophy on a Champ can be good...especially in rough water. Just like the Fury, the Trophy needs to be one p lower than the best Tempest Plus. A 26 Trophy may do what you want, but a 25, being more aggressive than the Tempest of the same size, might also accomplish lowering the rpms. As a general rule, our Champs prefer 3 blades for best performance, but you really need to continue experimenting.
