Driving after new springs

Going to fit my eibachs today at my cousins house and there are two routes I can take back one is kinda bumpy and over some moorland and one is on Main roads and fairly smooth, does it matter which one I take back, do I need to let them settle on the smooth road or help them bed in on the bumpy one? Or does it not really matter? Thanks in advance
 
dont trash it though..if there is a problem you wouldnt want to find out while driving enthusiastically...
