My understanding of the Radar (haven't thrown it) by just looking at the numbers would be that it would be similar to the Action by Columbia, a stronger, somewhat early reactive with a decent backend. The Horizon would be more similar to a flippier (and cheaper!) Inferno (same color scheme too...lol), one could feasibly make a good one-two punch out of the Radar and the Horizon
But that's just my two cents, remember I haven't thrown (or seen for that matter...) the Radar, this is just my speculation based purely on numbers.
