Copper Fin Heating

ultimatetouch

I recently built a two story addition. I am getting mixed opinions on the installation of the copper finned radiators. I would like to make sure whoever I choose to hire does it correctly.
Guy1: Will run 1" pipe with one 3/4" loop going back to a seperate pump from the boiler. This pump and zone will feed the entire two story addition which includes multiple rooms.
Guy 2: Will run 2 seperate zones on two thermostats. One zone and thermostat up and one zone and thermostat down. This guy will run seperate 1/2" loops to every radiator in every room returning back to the boiler.

Copper finned rads. Or copper finned baseboard? Big difference.

What BTU are the rads/baseboards?
