Sandy Corridor Routes

Has anyone put up a route or climbed the wall on the left side of the Sandy corridor? When entering the canyon on the left side there looks to be some routes that might go.

I guess more specifically I was wondering if anyone has climbed the two giant sweeping arches on the left side of the corridor as you enter. They looked like they would go but I didn't have the time to try it out.

As I get ready to head out to Red Rocks at the end of April here, I have a few questions for some locals that can help me out.
1) Anyone climb either of the two sweeping left arches on the far wall (near the entrance) in the Sandy Corridor yet?
2) Whats the rules regarding pins. I know there is no fixed gear but what about pins (since they can be removed)?

Feel free to berate me and tell me to not climb it and wait until someone strong enough does. But regardless I would like to try and climb it. (aid or free)

Thanks
