I've got to tell you, I actually got a little excited when I saw this topic back on the front page.
I have to say, from the video I'm finding it pretty hard to pick any faults - it seems incredibly accurate to style, especially the awkwardness of some of the banking that feels exactly like GCI awkwardness, even down to the slight bank on the end brake run. The sheer amount of work that must have gone into the support structure is also very commendable, they look very awesome.
I do hope you can find the time to finish it, because I want to ride it!
Not very accurate compared to their new ones but it's fairly close to circa 2006-2008 shaping, which is when I actually built it. It has some weird radii that the jerky video exaggerates a lot, but it is pretty smooth overall.
You can tell it's smooth. It's just that slightly awkward way GCI like to hold their banking a little as track also moves vertically - hard to explain exactly what I mean, but you nailed it anyway
