Well I was really asking more about going UP the hill, not down it. Going 55 to 50 up some of these hills would probably make me downshift to 4th...I was wondering how exactly to negotiate that. Like should I stay in 5th for a while as I slow down from 55 to 50 then downshift and hold speed (no way I'll be under 50 going up these hills)? Should I just get into 4th at the start of the hill? I know the best thing to do will be experiment, so I'll figure it out, but just any spare wisdom anyone has....

As for coasting down hills, there are no hills that I go excessively fast on (not more than 5 over the speed limit) coasting in neutral. Wouldn't it be better to let myself get going faster downhill and use that momentum to stay in neutral up the hill for a little bit until I'm getting under 60 and then get back into gear? I know that is true at lower speeds, but at high speeds does the drag make so much difference I'd be better off engine breaking in 5th (so using zero fuel but speeding up less)?
