Thats a creative trick, Darin.K... the extra bit of coding, however, makes it undesirable for me. I'd rather just make the labels external to the array and turn off the labels within the array.
What I think I'm going to suggest to NI is they add a few properties that are modifiers to the Label property of an array of clusters controls. There could be modifiers such as .First, .Odd, and .Even as exists in other programming languages (specifically the .NET languages). It would probably be a mess on their end to code, but it should would help the aethestics of LabVIEW (which is somewhat of an upward battle).
