Dunlop tennis balls: larger than the rest?

[killer]

I was playing som dubs the other day with a can of Dunlops and a can of Penns, and it seemed to me that after a couple of sets, the Dunlop balls appeared larger than the Penns. Anyone know the diameter differences between these two? How do other balls stack up in terms of size differences? Cheers.

Measure them and report back.
