I have thrown both and the Reax2 is reads earlier and can handle more oil. It is quite clean for an asym and has a strong arc at the breakpoint but I wouldn't consider it skid/snap. I see it being quite close to the Hell Raiser Terror.
The Yeti Untamed is clearly longer and makes a much harder move off of the friction. It is flippier than my Diva but with a similar amount of overall hook.
