Tbh, based on the stunt preview video, I don't think it's the front flip ramp. I think it's either the ramp modified or a new ramp he is using to jump the 5 trucks. It looked like that same ramp from the preview.
I'm really liking the purple one, I'm starting to not like the orange one.
Also, lets not worry about the track too much. World Finals 16 was a better track than World Finals 15, so maybe the trend will continue.
Steve Koehler doesn't drive Wrecking Crew this season, Dave Radzierez (owner/driver of XDP) drives it. Steve has been filling in for Feld trucks since he is available.
As for Crushstation, since he was at a show in New England, something something something lobster. Something about lobsters and New England.
Happens to me to, I believe it has to do with the material file and how it's set up, but I have not found a solution yet. However, as more people start working in 0.4, I'm sure we'll solve this issue soon.
