I think those are good ideas. Also, I think the earlier version of A is with the connection from Mid to A feels better. Move the A Long connector entrance up closer to where the driveway swings right, and now the CT's have another angle to worry about rotating T's. I think this will put emphasis on the angle into the site and solidify that choke point.
Happy to help with play testing or anything else if you need just drop me a message.
Also, congrats!!
