The new Arson Hybrid is almost as strong as the original from what I saw in the review videos. But, it is still going to have less overall hook and a weaker cover than what you'll have in the Ratchet.
Big difference between both is that the Wrench will be a 100% pearl cover compared to the hybrid on the Arson. The overall FCC ratings are the same at 19 from what the Hammer site says.
If you go with the Arson Hybrid, I think it's more of a transition ball. Start with the Ratchet, and as the pattern starts to blow up, move down to the Arson Hybrid. Then from that point, ball down as needed.
It just depends on the type of reaction you want. Do you want a smoother reaction with the hybrid cover or are you looking for more skid/snap with the pearl?
