I have some Bennetts. 14"x10"ish I think w/ dual rams & indicators. Great for crosswinds & uneven loads. Many others out there, I think my sizing is right. I rarely use them, except in nasty weather or main channel @ Lake Powell or lots of fat chicks! . They work like a million, brings the nose way down & can reduce my plane speed. W/ my larger prop, I fall off plane @ 30ish. Tabs can get me to 25ish. Sure screws the MPG's.
