I checked the balance today being that it's been snowing and raining for the last few days and after balancing - 1 silver and 1 black were off, so after I added some clear finger nail polish to the light sides, I just put the old set in the bag and brought out the stock spares that came with my P3A today. The spares are a perfectly balanced stock new DJI factory set and now my original used set has been rebalanced and have gone into the spare prop bag.
I have the Speedy Prop Balancer with a bubble level that I set on the main plate between the arms and then I set a kleenex on the table beneath it and moved it front to back and left to right to easily level it. The bubble level made it really easy.
