I think you're misunderstanding what some of us said about the Cheetah being harder.  The Cheetah IS harder than it used to be.  It's not, however, the hardest pattern in the world by a lot.  Yes, the version of the Cheetah that I bowled on this past season in my PBA Experience league played very tough for most of us, but that's only one version of it.  Remember, multiple versions of the pattern are laid out during the season, not to mention the patterns change every single day in a PBA event, as we've noted several times.  (Remember, the scores were pretty awful yesterday in the TQR until they tweaked the pattern)  We're not talking about something like the US Open pattern here.  Scores are pretty much almost always going to be within about a 20-30 pin window with all the normal sport-compliant patterns depending on the characteristics of the house.
