#1 - Chang. Big, fast, long, well paced. excellent overall, as you would expect from B&M.
#2 - Iron Wolf. Great, but too short. It was getting painful to the point where I would skip it, but new head padding has improved the ride greatly.
#3 - King Cobra. I don't remember it being painful, but seeing as it was the first stand up coaster I had ridden, I was probably too busy enjoying the ride to notice.
I haven't ridden any other Stand Ups, so no comment on the rest of them.
