On the fleece side, the main practical difference
is that the suri is often only sheared once every two years.However, they probably should be sheared every year (for Vitamin D production and to avoid over-heating) - whereas
the huacaya should be shorn annually.
Comparing the two fleece styles:-
The suri fleece is mainly described in terms of lock style
and lustre.
The huacaya fleece is normally described in terms of lock structure,
crimp and brightness.
