Invincible calves?

[SPL]

I searched the forum for some info on Invincible, but there was nothing very relevant, and most posts were over a year old.  Has anyone seen very many calves by him lately?  If so, how are they feeding?  We had seven this year with one standout that was out of a Kadabra/Chill Factor.  They seem to have a lot more grow in them than Heat Wave's.
