Tog, you are certainly on the right track, but there is really no need to cehck to see if you have a hanging burr.
The OP should just ruse a stone to remove it and then go skis the skis and see if there is any difference.
For the OP,
Put skis in a vise side edge up base away from you.
Take and arkansas or ceramic or any flat stone and place it flat against the base edge with about 1/3 of the stone sticking up above the side edge.
Using your thumb as a sort of guide on the side wall of the ski run the stone with medium pressure and in flat contact against the entire length of the edge. Make a couple of good passes . Pay attention to the any sound emantaing from the stone/edge contact and pay special attention to the contact points in the tip and tail.
As last step fro an ultra smooth edge take a hard blue gummi stone at a 45 degree angle with ABSOLUTELY NO PRESSURE and run it down the edge point.
Go try the ski and see if the perform properly.
There is absolutely nothing wrong with using a true clean 1 degree base bevel.
But I would highly recommend changing the side edge to a 3 degree!
