Are there the same pitching options with a cantenary cut tarp as with a flat tarp. What I seem to be looking at is that cantenary tarps pitch taughter have less pitching options and flat tarps flap but have more options. Can anyone enlighten me?

I think you're pretty much restricted to A-pitches if you want to take advantage of the design aspects of a cat-tarp. That said, you can probably do things like lean-to s as well, just don't expect the same level of wind stability.
