Polish is a tough thing to get right. Some polishes are better left to spare balls, and others are great for what you are trying to do. First of all, you can polish the ball too much. My first guess is that you are not putting enough pressure on the 500 grit abralon pad, or too much pressure with the extreme dull. Your base coat, in this case 500 grit should be with firm (not jamming) pressure. Every step after that should be with very light pressure. I like Storm Step 3 polish for my high gloss finish. I hit it with 500 grit 4 sides, a very light 1000 on 4 sides, and then step 3 polish on two sides only. This gets the clean front end, clean mid lane, but doesn't sacrifice back end reaction.
