Sounds like a good reason to support companies like CP, Ross and RaceTech pistons, and Molnar, Scat and Eagle for cranks & rods.
From what I've seen, CP and RaceTech BBM pistons are a generation ahead of the stuff that Diamond and Wiseco offer. I like Mahle, too, but it's all 4032 alloy for BBM and the selection is pretty limited (e.g., no dish or dome options).
Maybe thats what you have seen.. myself.. I bought
a set of Diamonds the last time I bought.. they
were very nice.. I did have some custom specs to
them and I picked them up in 3 days.. the numbers
were right on and the finish was very nice.. they
didnt looked as good as my PCs or at least damn close
