Hi Rob,
The only bit of 'wisdom' from personal experience is the 60 A has the
field connector is a location that I could not fit it in my cowling.  So
I had to drop down to the 40 A unit.  I didn't really need the 60 A
anyway in my VFR 235/320.  I'm the guy scared of lightning don't ya
know.....  :)  Earl
