1500 polished is accomplished by sanding the ball to 500 or so and then applying Storm's Step 2. You'd need a spinner for optimum results.
My Rapid Fire has the strongest layout in my bag. Even with the layout it has more length then my weaker drilled Sure Fire and more back end by far!
I use mine as a benchmark, because I can tell really quickly if it's too strong off the end of the pattern and I can move to my Paradigm or T-Road Pearl.
It's been a great med/heavy ball for me in the box finish.
I shot my first 800 with it (855) last month and wouldn't you know it, the oil machine goes south and the center goes out and buys a new oil machine and oil the next week (Bruns A22)! Much lighter shot now, so the Rapid sits in my bag.
