Colossus, Thorpe Park: I used to really dislike this ride because of its roughness but when I found seats that weren't rough I started to really enjoy and it became my favourite coaster at thorpe
Eurosat, Europa park: when I first rode when I was about 7 I really hated it but in more recent years I have grown to tolerate the roughness and enjoy the ride.
Nemesis, Alton Towers: I never disliked this ride but I never used to think it was amazing until recently when I discovered the back rows ultimate intense which made it my second favourite invert behind montu.
