I know RWA offers a 30-day money back policy. See if Rogue offers the same, and then try 'em both and keep the one that you prefer the sound of. I would think your spekaers are going to sound best with the 70.2s as i remember that they are 4-ohm and can use the extra power. I couldn't be happier with my RWA gear and it should at least be on your audition list.
Good luck,
