My stats: 16.5 mph ball speed, 285-315 rev rate, up the back type release with a high track. To summarize, medium speed - forward roll type of release with moderate revs.
I put the INTENSE FIRE at 55 x 4.5 x 35. This layout ended up with close to 2 oz of side weight which now doesn't require a weight hole as of August 1, 2018. I may still add one as I doubt that I will have this come 2020 when weight holes are eradicated from the game. I may add one to get this one to slow down some on the back.
I have used my INTENSE FIRE on many house and some on longer sport conditions. On the longer sport, it was squirty in box finish. A quick hit with a 2000 pad took a lot of that right out of play. The pad helped blend the heavy push in the front down to where the back end wasn't so jumpy when the INTENSE FIRE seen the friction of the end of the pattern. On house, the INTENSE FIRE is mucho ball. It really comes off the friction at the end of the pattern hard almost uncontrollably. The 2000 pad really helped to get it to slow down some but if I just use it in league play, I may need to smooth that up to 2000/4000 to get the ball to lane shine.
Compared to other piece in my bag and progression: I have been also using the new RG HALO. I am positioning the INTENSE FIRE as the ball down from the HALO when I am moving left away from the pocket. I have the original INTENSE also. I see the FIRE with the 2000 as much earlier and the INTENSE is a good ball down for my game when the FIRE is starting to dig in too hard and I want to keep a strong shape downlane.
I think that straigher/tweener players will like this one. Get the shine knocked down to suit your game if this one plays squirty out of the box. Power players may not like the hard backend of this one and may want to tone down their layouts on this one. All in all looks like a great compliment to the original and to someone wanting a ball down option from their big hitters in the bag.
