Gene,
I don't think you could use it for a true dry condition. I own one of these and have it lightly polished, using it as my medium condition ball.
Brian Purcel with track e-mailed me the info he had on this ball. The cover is supposed to be the "power plus" reactive and the core is akin to the old columbia rage without the flipblocks. These were his exact words.
If this is true, that would put it close to the strength of the freak-a-zoid, and I have a video comparing the orange slash, heat, blue slash, and desert heat. The orange slash is played deeper on the lane than any of the others and has a strong move at the breakpoint. This is not a video of me, but one that I found on here. You might do a search for video and find it.
In practice, this is the very same reaction I get here. Good length and pretty hard move at the break. I have my feet lined up on the 33rd board, sliding at 30, targeting the 3rd arrow. The ball gets through the heads really clean and has PLENTY of recovery to make it back to the hole.
I also have an ebonite ice to compare it with and the orange slash has more recovery with the surface in a similar state.
