Cleveland CG Red
Good players want responsive feel and handling from their irons.
If this sounds like you, then you want to know when you mis-hit a
shot, why you did, and by how much. The CG Red incorporates a
lightweight viscoelastic dampener directly behind the sweet spot
(in red). But this one is slightly firmer than the "gelback" used in
CG Gold irons. So it eliminates some unpleasantness but doesn't
totally stamp out feedback.
