All I can say is please, pleeeeeeeeaaaaase make sure the Armco (if there is any) works, two awesome hill climb tracks (Project Kaido's Akagi Mountain and Shomaru Pass) were ruined by barriers that would either destroy the car at the slightest touch, flip the car over, glitch it through the floor or simply fail to stop it from flying right off the side of the mountain. I can't even begin to think of pushing hard on Shomaru Pass mainly because I've only finished it about five times (so I'm very unfamiliar with it), the rest of the time I've accidentally tapped the barrier and had a massive accident or something. It's great apart from that but it doesn't look like they'll be fixed.
I think point-to-point courses are by far my favourite thing to drive on, I don't really know why but I presume it's because I prefer tight, technical stages to most circuits, you rarely get rally stage-style circuits after all.
Anyway, enough rambling, what I'm saying is I'm really looking forward to seeing what you come up with and I can't wait to blast up/down/around it in a Z-car or N2 Levin or something.
