Cooling and condensation

I know that this forum is for hydronics but I am sure you have been involved with this issue in the field.
I plan on heating with a boiler and baseboard radiation. Cooling will be a air handler in the attic with a plenum and duct system in the attic.
The house: only 26x33, crawl space, 1 and a half story, collar attic on top and knee wall attics on the sides, 12/12 roof pitch, 2x10 rafters, floor joists for second floor(ceiling joists 1st floor) are 12" TGI's.
My plan to cool the downstairs is to run 6" oval ducts in several of the sloped rafter cavities from the upper attic to the knee wall attics then through the ceiling with ceiling registers.
The sloped rafter cavities(2x10's and about 8' long) will each have baffles for ventilation. The baffles will take up 1" of that space. 6" oval ducts are 3 and a half inches high. The rest of the space will be blown cellulose(Hi-dense). The finished ceiling will be drywall.
Should I be concerned with the ducts in the sloped rafter cavities "sweating". Can anything be done to the metal oval ducts to prevent such a thing.
I am in Indiana.
And thanks for the previous replies regarding toe-kick heaters

wrap them
Those cooling ducts can be wrapped with foil faced insulation when installed to aleviate your condensation concern. Enjoy...Dan
