Significance of Peruvian, Bolivian, Chilean?

Delurking: My husband and I are seriously considering purchasing a
couple of alpacas for our younger son to take as a 4-H project. We
have visited two alpaca farms, done a bit of research on proper animal
husbandry for alpacas, and such. We have a small farm, grow our own
hay, and own some livestock already, so having the facilities to house
the alpacas isn't an issue. I've visited www.alpacanation.com several
times.

Our son prefers the suryi type of alpaca. However, I haven't seen any
discussion--or maybe I've just missed it--on the significance (or
preference) regarding the Chilean, Bolivian, or Peruvian lines. I'd
like to be an informed buyer before writing the check.

Would anyone please explain the pros and cons, if any, among those
lines?

Thank you in advance.

Sincerely,

Karen Smith
