Which rocker2 are you considering? The older Rocker2 90's or the newer Rocker2 100's? The 90's are way more of a park ski (a redesign of the tweenty12), and the 100's can rip anything (see Bobby Browns latest edit) Either way they are both narrower under waist than the Blog (110mm) The 100's will have the most amount of rocker if that's what your looking for. I am currently skiing on Blogs and and have made many laps through the park with them and the edges have help up very well. If I had to choose between the Blog and the Rocker2 100 for park I would pick the Rocker2 100's. Hope that helps.
