I rarely use polishes with their slip agents. I prefer to take a ball to 500 or 1000 then use one of the great compounds (Crown compound or Storm #2 get lots of use) for some length but a better read of the friction.
Also, now we have access to some very good abrasives around 5000 grit that work great with water and higher speed on the spinner. Each step you add, for example 500, 1000, 2000, 4000, 5000 will add length on the lanes as opposed to 500 and skipping directly to 2000.
Don't be afraid to experiment. Only you can see your ball motion and what you're trying to create. If you go too far one direction, you can change and learn.
As a general rule don't be afraid of adding surface unless you roll it slowly. No ball ever made will hook in any volume of oil. Every ball needs to find some friction before it can change direction. Best of luck as you move forward.
