Sac... little carried away with the "123" deal?
I never said that a bus would not cruise "all day long" at .80.... it just seems like .78 is the norm while the 73ng's seem to be .79-80.... just my observation. In fact, it always seem like the last leg home it (the bus) will do .81 fairly well
What ever a/c gives you the best QOL is better...... as far as I'm concerned.
Cheers,
