Gomer...
212man and I have done the "Rat Killing" shuttle flying in 212's, hopping from well head to well head, and you can see from his post that we share the belief that such work can be done with a twin as well as a single.
I agree with everything 212man said about this...it really is a philosophical view that requires examination as to whether twins are better than singles. Bob Suggs, et al, reduced helicopter flying to the lowest denominator by adhering to the Bell 47 mindset that PHI started with....just like the way the offshore boats evolved from Shrimp Boats. The GOM is its own worst enemy at times....small decks do not allow for "bigger" helicopters thus singles get forced upon us....answer would have been to have better foresight and build bigger...safer...decks.
