They are so hard to find, my Clydesdale x tb is 15 now, and I am not looking forward to eventually having to find a replacement (touch wood he has many more years ahead!).
I do think for riding horses heavy crosses are great. The heavy side often gives great temperament and attitude, and the cross gives that bit of a finer frame. Charlie has all the moves of his Hannovarian Dad so finds dressage moves easy, he jumps like a stag, but we can go out for a hack with a group in the forest and he is the sensible one in the group. I think you also get the same qualities when crossing with our lovely native breeds.
Lucyad, what a lovely picture, hope that is on the mantle.
I do think it should be mentioned that 'gentle giants' are made not born. It is very easy to see the magnificent heavies doing their work and termed as gentle giants. Behind these horses are real horsemen who school and train their horses with immense skill and knowledge.
I took on a Shire x Cob yearling and thought it would be a dope on a rope. I could not have been more wrong and got very very close to giving up on him. I found the right people to break him in June and he is going the right way now. He will be at least 6 before he will be a made horse.
