i just throw my weight over the bars and look behind me. wet or dry, they're pretty fun, sometimes i feel safer doing them dry because in the wet i sometimes whip it around so fast that it catches me off balance. also, i think it's all in how you angle/torque the bike as you slide the 180. but the looking behind is what helped me. they're very practicaly for those moments you're biking one way, you see a friend biking another, and then you both spontaneously decide to turn around and stop for a chat.
