I like cruising between 70 and 85.
70 is good for economy, just under the power band and 80 is just in the power band. 85 starts to get noisy exhaust wise. Even, predictable response and handling from the car between those speeds to either acceleration, braking or to steering around any bumps/idiots that get in he way.
