is always keeping the RPM low bad for the engine in the long run?

You can easily cruise at 45 mph in 6th gear without lugging, but if you need to accelerate or go up a steep hill you would want to downshift to a more appropriate gear. If you have to floor it just to accelerate a little - you're lugging the engine. If the engine starts running rough and sputtering because you're in 6th gear and doing 15mph - you're lugging the engine.

I personally wouldn't recommend it if you are above sea level in a hilly/mountainous environment. I live in Georgia, and routinely travel roads with a 45 MPH limit, cruising in 6th. Just about every time someone slams on the brakes to turn (no signal, of course), I feel the car bog and have to shift on even the smaller inclines. I do have an 06 with slightly less low end torque, so that may be the factor for me.
I think the best thing to do is for each individual to be aware of how the car feels in the driving conditions they are in to decide whether to go to a lower gear.

Personally, I have the Z in 6th anything over 35-40 MPH, assuming the road is flat. And the Z has enough torque to make it up small inclines without flooring it at that speed. But don't worry, I go WOT everyday merging onto the highway.

I totally agree with you anyway...

getting on it often is a good idea for the purpose of preventing vcarbon build-up. These engines were made to run at high rpm's consistantly. I would NOT hit your rev limiter everyday though obviously. Carbon build-up is more of a problem on BMW's (M3's) which is also why they dont let them sit in one place to warm up for very long. Im sure theres other reasons why getting on it from time to time would be a positive thing but hey im no mechanic.
