Aaah, now I understand why the track felt not hard to me. It was because of the track material! Funnily, I even read your post but I still didn’t quite get it. xD
And
this looks like a track that deserves the “V”. Good idea to add new textures for this, it was about time that there are more textures for volcanic-themed tracks.

You did a great work on the terrain. Using fog for the volcanic atmosphere is a nice hack.

I was at first a bit skeptical of making 10% of the track on the ground but after seeing that this makes the track even more difficult, I am fully in favor in it. And this track is indeed way more difficult since the desert road was clearly a mistake.
I would say both rubberduck and CryHam have done a really awesome job. Rubberduck made an awesome track and CryHam made the terrain awesome. I like that. Thanks to both of you!
But, CryHam, I think you should not rename a thread like this. Adding the usual theme prefix like “V6” is okay to me but completely renaming it is not. Some users may have some trouble searching for “V6-HighDrive” now. When you rename a track like this, you should at least preserve the original track name in the thread title. For example, like “Y12-Blablabla (previously called ‘SomeRandomTrackName’)”.
