I wonder if it would be in order to hard-wire the bridge part of the 
circuit, and confine the controll circuit to the PCB.

I imagine 1mm by 5mm magnet wire (5/128 by 25/128 inch :-))
Or even really fancy jig-sawed busses to connect the FET`s with each other, 
the coil and the power supply.

That`s how I plan to do it, and water cooling is part of the sceme too, 
with "O" rings around the hole below each FET, for closest contact to the 
water.
But I am rampling, still have to finish that grounded cage, so that I might 
get reliable measurements.
