My truck presently has the externally resisted 12v coil and it does not have the by-pass switch on the 6v starter. My truck usually starts on the first crank. I live in south Florida but your weather isn't that extreme so you might be ok with the same setup. The by-pass switch is nice and I'll probably wire one into the circuit down the road. You can always pretend you have Lucas ignition and that hard starting is normal

Just kiddin', jon boy jonny.
