Just an FYI... CDIs do not (in general) invite competitors individually. The Sydney CDI is a 3*, meaning that the organizers have to invite a certain number of NFs (National Federations), and then competitors from those countries apply to their NFs with results from national and international level shows inside their home country and if the NF approves them, they may enter the CDI outside their home country...
Anyone getting individually "intived" to a CDI will not be getting "invited" as a competitor, but rather as an exibitor.... so to say this is proof that X horse does really great at dressage is like saying Madonna is a really great football player because she was invited to play at the half time show at the superbowl...
As I said previously, drafts can make decent lower level mounts, however, it takes an extraordinary horse and the right trainer to do the upper levels. Even if you can get the horse up there in training, it is not likely that with correct work (ie not just doing tricks) that the horse will stay sound. Drafts are built for pulling, not collection. Doing dressage, correctly, with them is like putting a square peg in a round hole.
Quoting the owner of the horse "Righto Peeps. Time to be serious here. Have had an invitation to attend Sydney CDI in May. Need to put my name forward by next Saturday. I am going to need some serious financial support to even contemplate this. Mother is strapped for cash over the indoor. We would both appreciate some serious fundraising ideas here....."
I'm afraid anebel - you are a dressage snob!
The one thing about a draft is it has the back end like a bus! They can and do collect very well, the initial move off for a draft with a heavy load is pushing - from the hind end not pulling.
If you have a horse with good conformation and action - my Clydesdale has a fabulous shoulder and length of neck, and moves as straight as a die! yoou can with the right trainer produce a GP level horse
Add a good trainer who takes their time the horse will be able to do most if not all the movements required.
Consider the horses from 'The Spanish Riding School' the stallions are used for high school work and the mares pull carriages!
As we are seeing with Totilas - the trainer/rider helps make the horse - his current rider is obviously newhere near the caliber of Edward Gal and the work produced sadly shows this.
