Couple of thoughts...
1. If at all possible do the edge detailing on a bench. Palm sander or orbital will do the trick. If you can get two guys on the project setup a 4x8 sheet of ply on saw horses. Go through and break the bands on 5-6 nests of flooring and set it out on a pallet loose. If you have a forklift, put it on a pallet waist high by one end of the table perpendicular to it. First guy grabs piece off the loose pallet and edge details one end and the side facing them then he slides it across the plywood to the guy on the other side who details the other end and the side facing him. You can move pretty quickly through a stack like this.
2. Heavier the scraper the better. In OKC guys are still scraping every other unfinished job so the contractors have all gotten quite inventive on the scrapers. Think lots of lead weights.
3. Wet wiping can help if you have a harder species.
4. Screen using a white pad underneath so it will follow the contours of your work.
5. Try not to have a guilty conscience since you just got someone to pay you more for a floor that you shortened the lifespan of by 30 years.
