pjr300, if you go to Big B they think that the Ultimate hooks very slightly sooner and slightly more arcy BUT harder, than the Raging. The Raging, because it's polished and because it's a particle, goes a little longer but has a more angular entry. My read from what I see is that these new solid reactives have a very hard, continuous arc. The strength of the cover (and core) makes me think that they would be more predictable than particles and less susceptible to over/under. I'm sure that someone that knows WAY more than me about this stuff might see it differently and maybe can explain it better than me.
