The first polled bull that I remember using was Fair Weather Charlie-P about 20 years ago?  We had a few daughters from him and they kicked like mad!  They acted so crazy in the parlor that we could not milk them and they all left shortly after calving.  I don't think that we have any decendents of Charlie now.

We didn't really consider any more polled bulls until Honour-P came out.  I have some really nice daughters from him in the herd now including a polled 88 point 3 year old that is scheduled to have 22,300# of milk this lactation.  I have her bred to Eclipes-P and hope to get a homozygous son or daughter out of her.
