Formula Feed Babies = Heavywetters?

I just learned about this last night and wonder how true it is? My dd is on formula and I didn't breastfeed exclusively and she IS a heavywetter... the super one! I had heard from other breastfeeding mums that their children are not heavywetter and thus have no problem using pocket diaper with 1 insert or the most 2 inserts.

I'm wondering whether this is so true? I shall try to breastfeed (bf) exclusively for my future baby and see the difference on their wetting. So, your baby on formula or breast milk? Do you agree on breast feed baby has lesser wetting (I mean in volume...)?
