That sounds like a good plan to me. My pair would be about 31" and for some reason I have found that to be significantly different, power-wise, than even my 34" mini. But I'll bet two of them can do it. I'm thinking of getting the single seat VSE cart (very small equine) cart made by Lignite Carriages. It is only 78 lbs. Thanks for your advice! Karen I'm thinking you should try the pair first. You will be surprised how much power you have compared to a single (provided your carriage isn't too heavy). As far as I know, driving a unicorn is much like a tandem, the leader shouldn't really be pulling (in draft) much anyway, and would be much more difficult to drive. So you might not have an advantage over the pair. Neck collars are a good idea, but only if they fit well. That's really hard to do on the little guys. I drive a pair of 38", and they can go pretty much anywhere. Where we live is fairly hilly, but they're rolling hills, not steep ones. They handle it well. We use breastcollars. If you still want to try the unicorn after fully exploring the pair, then go for it! Welcome to the list, Rachel in BC I am sorry this is so long-winded; I am usually a more succinct poster, but I do have a question which precipitated my joining this list. I have been disappointed that I cannot drive my minis in our terrain. I am thinking that driving a pair or better yet, unicorn, with all in neck collars, would allow me to cart them around the hills here. I have never seen a unicorn setup, however, and need to know what is involved from the equipment and temperament standpoint, all pros and cons, etc. before I take the next leap. Any guidance, direction, links, etc. would be appreciated. Thanks for listening.
