I have one but I can't remember if Lux Z is his sire or grand sire. I think he is his sire but will check tonight and let you know.
My horse has a good temperament - he is usually ok but can be a bit sharp if he has had time off work or is doing something exciting. Put it this way, I would not want to gallop him across open fields in his snaffle!
I bought my horse cheap because his previous owner (who used him as a showjumper) was having problems with him napping and refusing at jumps. I now only really use him for dressage with the occasional bit of jumping for fun. He is naturally a bit nappy but once you convince him that he has got to work, he really is the best horse to ride and generally stays in front of the the leg and switched on.
He is good to handle on the ground and lets me do anything with him.
Me me me! They are extremely intelligent, quite sharp, very smart, mine moves fab BUT they are notorious for being slow to mature physically and mentally! My trainer jumped at the world games when Lux Z was competing and he says he was always in the collecting ring working the horses exerberance out! I would definately have another although not if I was in a hurry to compete a lot in the early years. Tell us more! x
