Packraft paddles: big v. small blade, high v. low cadence

Two questions which are perhaps only sometimes related.

Do folks perfer a large surface area blade for packrafting, a small blade, or something in the middle? To what extent does whitewater v. flatwater v. expedition use influence the above?

High cadence v. low? Again, parsed for different uses.

I assumed I want a big blade given the premium on maneuverability, and the lack of need for sustained high speed, and my Aquabound Shred has never been lacking (except in stiffness). Curious what others think.
