It's partly that - the lack of Nemesis, Nemesis Inferno, Swarm and Ultimate (it's not like your UK top ten is full, after all) is surprising.
It's also that you rank Stealth as your second favourite UK coaster and Saw as your third favourite UK coaster, and they're seventh and ninth favourite overall, but Icon doesn't appear in your overall rankings at all. Different ranking criteria? Out of date overall top 10? Something else?
Oh wow, I seriously need to update my Top 10! The Icon top position is based on some incredible night rides I had very recently tbf.
I also think part of the issue is, I'm just so easily suade!
One excellent ride on a coaster is enough for me to fall in love with it all over again. So my top tens and favourites change all the time. And sometimes I find it hard to distinguish between a favourite coaster and a best coaster, if you know what I mean. Coasters that are either subjectively or objectively good.
Maybe one day I will understand my own wacky coaster taste!
