Cleveland CG7 Tour Black Pearl or Ping i15?

These are the two sets of irons i'm deciding between. I have hit both indoors. I was origionaly set on the i15s, but discovered the clevelands and now like them too. I think the clevelands look way better, especially with the black pearl finish. I read that the ball flight on the clevelands is a little higher because of the amount of spin the grooves get. Just hoping someone out there knows a little more about how these compare than i do and has had some experience on the course with either.
