Rode front row on Colossus for the first time this season, and I was shocked about how smooth it was. Not sure if they have just genuinely improved it somehow or it was just because we were front row but we didn't bang our head once. Yes the train was vibrating quite a bit but that doesn't bother me at all. Didn't ride it again that day as it was running 1 train, and wasn't up for waiting 80 minutes for it but it was certainly the best ride I have ever had on Colossus. I do feel Colossus is quite under rated by most people, I defiantly think it is the best coaster at the park.
We weren't actually going to go on front row, but it broke down and everyone left, only 4 people were left in the station and no one was at front row, so we thought we might as well Glad I did now though.
