I love connies!! Best breed ever, they are athletic, intellegent, quirky and generaly all round fun ponies.
Whilst the vast majority love jumping some don't. My lad hated jumping however he found medium level (3rd level) dressage very easy.
There are 2 types of connie,
1) the good old fashioned type with a leg at each corner, up to weight and masses of good quality flat bone.
2) the finer sports horsey type. These have less bone, generaly pushing the height limit and look more of a horse than a pony. I am not a fan at all!
I would say that some connies are suitable for novices, some are most deffinatly not.
Stan my lad would have knocked the confidence of a novice and ground it into dust, when he was good he was very very very good and when worked in by an adult could be trusted in the show ring with a kid but without being worked in or if he was in a bad mood he would plant you face first into the dirt, Out on a hack he was very very quirky, jumping poles he didnt do at all and XC he was suicidal.
Anouther connie I knew (Gliss) was 14.2hh medium level dressage mare who needed to slow down, she bred 2 foals and then aged 15 my cousin bought her for her 6 yearold daughter. Gliss never put a foot out of line.
This was my lad Ballinasloe Hero - (stable name Stan), he is a good old fashioned type.
And just prooving he was not a kids pony (he decided to take hold and race the 17hh hunter that we were in the championship with!)
