Actually, it looks like a GCI, all the way. I kind of remember hearing somewhere, Eastcoaster maybe, that GCI was contacted early on for this coaster. Don't recall the details, but obviously they are not the ones building it.
However, it doesn't mean that they couldn't have proposed an idea that Kemah liked, and then Kemah decided to go with another company to build it. Just a thought.
From where I'm sitting, it seems extremely coincidental that a company that has made a name for themselves for one type of coaster, would just start to emulate another companies style.
It looks like GCI because this is the genre that GCI has specialized in. Anybody who knows TGG's and CCI's work knows that this ultimately is *not* going to ride anything like a GCI.
Or at least I think that's a very safe assumption. From my end this thing looks brutally, brutally aggressive. Not that I mean that in a bad way, but I don't think many people would describe any GCI that way, save for maybe Hershey's Wildcat.
Just look at Renegade or Troy and then look at this coaster. It's clear they're all twisters (or at least portions of Renegade) but the math looks vastly vastly different.
You all seem to be forgetting all of the coaster companies and designers that came long before GCI and TGG. For example the design for OZ Wildcat and KY Rumbler was partially influenced by Rye Playland's infamous AeroCoaster. I even see bits of the Rye woodie in Kemah's Bullet.
Given the very small plot of land Bullet is being build on it was going to be a twister no matter what company it came from.
GCI's tend to resemble interstate interchanges with track going all over the place with little to no parallel track moments. This ride wraps around itself over and over again. Almost every drop/hill on the ride is linear like on an out & back. There are no spiral drops like GCI layouts are usually full of. IMO, this layout is distinctly not a GCI.
