I did use my bike, everyone that was in the class did. We had 18 people, 3 bikes hit the asphalt, but not mine. I did get a little cocky on my last run through "the intersection", tried to go a little faster than my skill level and did stumble at one point but I was able to correct and finish the circuit without incident.
A small group from my HOG chapter gets together on Thursday nights to practice. The prep definitely helped me get through the course without looking like an idiot. I definitely wasn't the best rider in the class but I was in the top half. I was happy with my performance but I will be practicing a lot to hone what I learned.
The biggest thing I took from the course was confidence. It's cool to know I can make a right or left u-turn in less than 20 feet. No more waiting for intersections or parking lots, or fields, or.....just saying "the hell with it" and keep going in the wrong direction. 
I took the Atlanta Based RLAP class in East TN. It was a great class. There were 11 bikes, 2 were 12 CVO Kings, a CVO Ultra and all but one touring bikes.
I was shocked at the number that had extreme difficulty with the 24" circle or cross roads with the 4 u turns.
I was a bit nervous about dropping my bike, so I took the bags off and put protectors on the engine guards. Never dropped it.
We did have two bikes dropped. By the end of the class I was able to ride the circle a couple times with the bars at full lock. I can consistently do the circle in either direction in side 22 feet. My goal is to get to 18 by next summer.
I am just glad my wife can do a 22 foot wide U-turn on her street glide.

However she sometimes gets pissed when I do it when leading a ride, as none of her friends can and most my friends can't either.
I think everyone should take the class.
I have marked 24, 22, 20 diameter spots in my cul-de-sac. I am ordering the little cones so my wife and I can practice. I will also re take the course a few times.
