I recently expanded into triple registered horses. I really like the Shetland look personally. I know some people dont feel there is a place for Shetlands in the "mini world", but essentially minis are a height registry, so if it measures in, its a mini plain and simple. (I realize AMHA is closing the books, but at this point, all it is is a height registry...) Recently there have been alot of A size Shetlands doing really well, from what I have seen watching the World show and National show. I also feel that Shetlands will be an important option when the dwarf tests come out (JMHO). I think the small Shetlands are another "branch" of minis, there are people that have falabellas, people that have appaloosas, people that have driving horses, etc. Its nice that we have so many options with minis to have what we like, and leave what we dont. I think the main "con" I anticipate is having offspring that may be over sized. But, those horses will still be aspc/amhr, so its not like they would lose their papers like an AMHA only horse that goes over. And I have seen many horses from 30" parents get to B size, so guess its hard guarantee size no matter what!
