Yes, put the transmission in gear, and let out the clutch to eliminate starter use.

If your main concern is fuel efficiency at steady state 70 mph, it makes no difference.
If you are going to pulse and glide around 70 go with the lightweight.
If you are going to be operating at slower speeds where you are limited be "lugging" go with the heavier flywheel.
Since you already own the lightweight, are not concerned with smoothness (NVH) I'd lean toward running the lightweight, but the decision is yours
