Hi,
I thin the 70s layout is cool - good work so far
Therefore I would like to correct my proposition about the modern version.
I think if the modern version is also build one of the slow first chicanes should be used. Best to use the firts one (green marking) so that one get an opportunity to overtake - that's quite hard if you have this very fast left-right combination (from 70s layout) because you have not to brake hard.
Besides, it would give more difference to the two tracks. The 70s layout is very fast (fast chicane and long long Mistral straight) and the modern layout is slower with good possibilities to overtake (first chicane and double-chicane (both green marked)).
Just a suggestion from me
Cheers
