80 grit? Are you sure?
If so, I suggest this is far too rough. The green nylon pad is about 600 grit. If you first sanded it to 80 grit, the green pad did not have any effect on the 80 grit grooves.
If you don't have a spinner, you need to take it to your pro shop, tell them what you did and ask them to take to at least 600 grit in the appropriate steps. Then try it on the lanes again. If it's still too early, ask them to take it to 1000 grit.
