We recently reviewed the Fire Road.
Our testers include a cranker (565 rpm), tweener (360 rpm), and stroker (300 rpm).
You can see the ball on a THS and sport pattern along with Digitrax Analysis compared to the Crossroad, Marvel Pearl, and Frantic.
http://tamerbowling.com/index.php/storm-fire-road-bowling-ball-review-with-digitrax-analysis/Storm has released the inverted Fe3 core with the R2X cover that's used on the Marvel Pearl. The cover is stronger than R2S so creates earlier friction than even the hybrid crossroad. This allows it to have a nice predictable motion overall. It's a little less "booming" than the Crossroad or HyRoad on the backends, but plenty strong. It covers very similar amount of boards to the Crossroad, but goes about it slightly differently.
All our testers easily found a very good look on the THS and were really happy with the overall motion. Our cranker had to be very deep but found less push than the Crossroad while getting a bit more controlled motion on the backend.
The Fire Road will also be a bit more usable on THS than the Marvel Pearl as the core is not as early rolling as the Centripetal core. We found it less prone to roll-out as the condition wore down.
Let me know what you think.
