Favorite breeds for packing?

[Missy]

Alpines-- Great body and size, lean build, best legs, love people, but have no goat-friends (aggressive to each other). 
LaMancha-- Great personality.  Large (mine is too thick for the job), no external ears so they're kinda deaf and dont shed heat via ears.  Well liked
Boer-- Can do the job but have short legs and barrel-body.  Sweet personality but not chosen for packing often.
Ober--A bit smaller, well built, epic horns, a little more independent personality.  Popular.
Nubian-- Super big, friendly.  Known to be sometimes lazy on the trail.  Loud.  Most people like this as a 25% mix or something rather than pure.
Togg-- Smallest.  Top-tier friendly.  Not that common in packing due to size but people that have them like them.
Kiko-- Some people swear by them.  Seem a bit boer-like to me.  Wide horns and sturdy
Krampus-- Best goat for pulling carts full of bad children.  Not generally friendly, but love kids.  For dinner.

Thank you for the rundown on each breed! My Boers are not fullbloods so they are pretty slight and have very long legs but can be a bit stubborn. Which breeds have you had and which was your favorite? I really appreciate your help!
