The main complaint against this Mack tower spinner isn't that it won’t be thrilling but that the concept is a poor fit for GAdv. Especially as a GP magnet compared to other potential alternatives. Its pretty much just a more advanced but reduced capacity version of Superman at SFMM. There is a reason why Lightning Loops, Chiller, and the aforementioned Superman were dual track. Personally I rather they wait and leave the space empty until they can put in a decent coaster than waste that space on this shuttle spinner.
