They have, I noticed. Didn't take any pics though.
Anyways, after my 10 rides on Sik today (across the whole train), I can honestly say that's the most intense coaster I've ever ridden, it really took a toll on me. I wanted to ride it more but I just couldn't, my thighs and stomach wouldn't allow it. It runs like a faster, better, slightly more refined version of Colossus, except for the quad heartline rolls which roll that fast it feels like Blue Fire's roll 4 times in a row (5 if we're counting the one before the station), and they literally make you feel like those water dummies from the first test run. Couple this with the thinnest lap bar I've ever seen on a thrill coaster and it made for what is in my opinion the most intense coaster in the UK. I've currently got it placed as my UK No. 6 and my No. 7 coaster overall, and in my opinion it's more than worth the visit to Flamingo Land to experience it, even if you've ridden Colossus (which honestly feels NOTHING like this). It's an incredible coaster but it's absolutely not for the faint of heart. It's surprisingly smooth too (except for the transitions in and out of the cobra roll where the train shakes badly for no apparent reason, but apart from that it's smooth as glass).
TLDR: Sik is imo the most intense coaster in the UK and it's definitely worth going out to experience it, regardless of what you think of the park it's at.
