The main problem for me was that the constant violence and sheer length of the ride kinda puts a number on you, especially on the return run. It didn't help that the lap bar kept tightening on the first few valleys. I couldn't figure out the best place to sit as well. Front was a bit smoother but the airtime was underwhelming, whereas the back is obviously more intense but got more violent. Of course it didn't help that I had high expectations going into it as well.
I've yet to try it in the dark though. I'm hoping to make the CF Live this summer and give it a second chance, possibly squeeze in some night rides as well.
