At this point I am almost half way through my vacation and the Farrell Hair Replacement System has held up beautifully. Today is the day I do the big roller coaster test. Since I have worn a Farrell System for almost two years now, I have ridden a few roller coasters and there has never been a problem. However the roller coaster I will ride today is a hypercoaster called the Steel Eel. This ride has a 15 story drop and gets up to 65 mph. According to the Sea World website, the main difference between a roller coaster and a hypercoaster is the amount of air time and weightlessness you feel with a hypercoaster.
