I would think that the Road Hawg and Raw Hammer Pain would be too close to have both of them, but then what do I know. Instead of the Road Hawg you might just get a Hawg, or a Hawg Zilla for the heavy stuff. Otherwise...the Pain handles the medium/heavy, Black Widow the medium, the Doom the medium/light, and the Big Blue Pearl....I don't know..never had any success with that ball myself. You might consider a Vibe for the dryer lane conditions.
