I think, like all man made breeds, there is a huge degree of variation. The modern traveller wants a short coupled min version of a larger horse, that can live on a small plot, it's about looks, so pretty colours, red and white, duns, champagnes colours are in with masses amount and feather.
Then there are the solids, usually with long silky white feather, add drivers, which are high stepping and tend to be bigger, and those with the pretty colours.
My main concern with any breed is that a lot are bred for looks, not how long they can have a healthy life. My biggest bug bear with small breeds, is they compress them, so their back is so short there is little room for a saddle, especially Welsh A.
I have mainly native, I have a Connemara x CHAPS cob, with a moderate about of feather, and I think its the best of both, good movement, cheap to keep, and unless its really muddy his feathers look pretty good. He can grow a massive mane if left, but then he live out 24/7 in all weather unrugged. He no harder to look after than the Highland.
