Friction bearing VS frictionless

Friction bearing VS frictionless

(OP)
Not sure which kind to use. The engine should only be spinning in the 6500 rpm area. The oil will be pressurized in either use but would a fog spray for frictionless bearings have less loss or other benefits over the gallery fed friction bearings?
Being a radial engine have all those connecting rods to oil from the spider. 2 rows of 5 cylinders. Seems a power gain and simplicity to use an oil fog like 2-cycles use instead of the drilled passages route.
 For an example the rods aren't split but 1 piece. A pin holds them like the pin in the piston.
This is a vertical shaft if it makes any difference.
