I concur with your other buddy.
My Smokin' and Rampage were drilled identically (2E) and were left in box condition. On every lane condition where I threw both balls, there was never more a board of difference in total hook. However, the Rampage was always a few feet longer, and somewhat sharper at the break, and thus seemed to work better for me when I had to go more away from the pocket.
Hope this helps.
