On a true reverse block, depending on the length, either play a board or 2 right of the friction (don't pull it!) Or get waaaaay left and play fall back. I just bowled a 5 game sweeper on Route 66, which is 45 feet, and I started out with my Dream On, balled down to a Night Hawk, and honestly should have balled down to a Boost, if I had thought to bring it. Keep the hook to the right of you, however you have to.
