I have not ridden roug, but i have mantis, and thought it was honestly fun. With vortex however, i hate that thing. its never worth riding and i always regret it if i do. And yes the lines are always because loading times. My absolute dream is to have it tossed over to MaAdv and we get a launched infinity. One could easily fit, but seeing cedar fair has only done a few things with Gerstlauer, i doubt it.
