Re: Orbital vs Sheet
I probably use my ROS 99% of the time over my finish sander. The ROS is more aggressive and cuts down on the amount of time it takes to sand. The random orbital action also leaves less swirl marks in the wood than a finish sander will. I personally prefer the finish sander for sanding edges and of course it also gets into corners better than a ROS. You probably should have both but if I had to only have one it would definitely be the ROS.
