The launch is slow... Right. OK. It's more intense then Stealth's by a mile, but whatever. Plus, it's faster.
It's too forceful? Too fast? Next will you tell me it's too good?
And you honestly think COLOSSUS has a better Inline? Baco's is full of floater airtime the entire way round, and is possibly the weirdest, most unique, and most spectacular inversion, certainly that I've been on, and probably ever. The whole "tunnel" thing? It's not even a thing on Baco.
The seating is pointless? Well, no. It makes the launch so much better, the turns better, the hill-thing better, the Inline better, the turn over the lake better. The whole ride, better. If that's not purposeful, I don't know what is.
So, if you could come up with a reason that makes sense and isn't completely stupid, I'm going to conclude that you are a silly Forpe fanboy who for some bizarre reason, thinks Colossus is better. I bet you didn't even ride Baco at the front, that's one of the best experiences around.
