You might want to think about getting yourself an edge gauge, sometimes called a skate edge checker, or a BAT (Blade Angle Tester) gauge. It will allow you to check if your newly sharpened edges are level. I know one sharpener who does a good job for one person, but an atrocious job for others. Do you know what hollow you use?
Oddly enough even some really good skaters don't care about the hollow. A friend who played pro level hockey has no idea of his hollow, he just asks the shop to put an edge on his blades!
