1) Intamin overbanked turns. Lean as hard as you can toward the ground while riding and KEEP looking down. Ohhhh yeah.
2) Morgan bunny hops -- provided they're not ruined by overbraking. What a sweet float.
3) Any good, tight, nasty helix. Raptor's finale and Iron Wolf's 'hoop around the loop' come to mind. Believe it or not, I even kinda like the 720 on the Cedar Creek Mine Ride.
4) B&M vertical loops, any variety
