The Blazing Inferno was a higher RG/Low Diff ball from a couple of seasons ago. If you can run one down, it might bring you pretty close to the Super Trooper.
I bought an used one off E-Bay to try out and it is very clean thru the front with a small read on the back. I have been using it on the scorched fronts & backs condition with good success. I also have a blank 15 LB in the box, I might be willing to part with as well. PM if interested.
