Hi Razor, no need for apologies, we all have the right to use whatever track we like! It is helpful though, if using a non-DLS asset, to provide a reference so people can go off and find it.
Re. your layout - I've really enjoyed 'super-detailing' it, but I didn't realise it's a prototypical one - having checked against the original, I like it even more! I hope you don't mind if I post some screenshots, which I'm going to distinguish by calling it 'Asburton', ie. a fictitious layout.
