Packing pedigree

[Namlots]

So, some of you may have seen my first post and that I'm new to all this. I have had goats that I have cared for but not pack goats. I have two nice alpine does and am looking for a buck to breed to them in the future. My question is how much does a good packing pedigree matter. If I find a good size buck that has the physical characteristics that I want is it going to make a difference if the kids are bottle fed and trained well or are they not going to be capable packers because of perhaps not having packing background? I'll try to scan through the forum to get as much info as I can but any info would be appreciated.
