Sense of Right League

I would like an opinion on something I've been mulling over for a couple of days. Do you think I should switch to standard isometric streets or should I stick with the curvy streets I have made so far? Curvy streets mean that making street markings and maybe curbs are a no-go. But I would like to try to map out my city pretty closely, and it seems like there aren't too many maps with curvy streets in them.
 

Hey, is there a mod that buffs log walls so that they aren't worse than normal wooden walls at high carpentry levels? Or could someone make it for me? I think that it's unbalanced for the log wall, which is made of 4 logs (12 planks = 4 normal walls) to be less resilient than the normal walls. Maybe an overall health boost too? I've read somewhere that the walls have equal health at carpentry 4 and then past that the normal walls are tougher... correct me if I'm wrong. Thank you
