I think zoning on harder tracks is a totally different experience from zoning on Anulpha and Syncopia. It's a different type of thrill even though your zone is not nearly as high. Reaching Zone 50 on Modesto Heights or Sebenco Climb reverse, for example, is scary stuff.

And yeah, I wish the programmers could allow you to make a zone battle goal of 75. What's the point of having a zone target of 15? Seriously? And I wish they would fix the leaderboards as well.
