I went for opening weekend and of course Boomerang wasn't open so...
My top are
1st: Mr. Freeze- Already had a great layout then going up the spike backwards and coming straight down makes it the best coaster.
2nd: Batman- Although it is a clone, the layout is too good to pass up and as usual is very smooth.
3rd: American Thunder- There is no such thing as a bad GCI. Lots of airtime and a rather good capacity.
4th: Mine Train- I didn't realize that other parks have Mine trains. I just assumed that since SFGAm didn't have one, none of the SF parks did.
5th: Ninja-From here the list goes down. Ninja is rough and Demon has never felt as smooth as when I think of this looper.
6th: Boss- This coaster is way overrated. I waited an hour for it and was the roughest wooden coaster I have been on. (that was until I went on Mean Streak at CP)
7th: Screamin Eagle- It was smoother than I expected. However, The layout made me really queasy and ultimately lost all of it's points for that.
