The thing I like about mattt's edit is that it keeps the pitlane entrace/exit traffic well out of the way of the racing line and also makes merging happen at an area with a low speed. SBF's design (and presumably Yannick's as well) seems to create pitlane exit/race line conflicts coming into that first square left-hander.
Just my 2 cents. This is my first post, I just found this place a little while ago so I'm not an expert
