I will be attempting, and hopefully completing, a roller coaster replica in my basement. I have found all the perfect materials and I know the designing that is required of the length/bend of each piece of track and each spport. But now I need help on which coaster to replicate. I will be using a circular tubing for the spine, and since this will be a replica, it can't be a Giovanola/B&M. Any suggestions that you would like to see built? I am thinking of either Steel Force, SROS (SFNE), SROS (SFA/DL), Vekoma SLC, or an Arrow mega looper (Viper/GASM). Any ideas?
