Need new fan clutch, which one to get?

[Lil Ape]

So the truck likes to run hot at idle or when not moving, and determined the fan clutch is bad(radiator, water pump, thermostat, coolant are all new) It really likes to freewheel. But I'm not sure which one to get between standard and heavy duty. I'm not sure whats even on the truck right now. It's purely a performance truck, no towing or hauling done with it. So I'm leaning toward the standard duty clutch cause I hear its better for performance. But being a truck and not a car, I'm not sure if i should go with the heavy duty because of the heavier weight. Plus, heavy duty is all that is listed when searching online for stock c10 parts.

Any opinions? Thanks.
