Sorry. Please remember that the only thing I know about your horse is a handful of photos on the internet, and that is not a complete picture by any means. I would be soliciting my vet's, farrier's and trainer's opinions as well, and giving them a lot more weight that a random stranger's on the internet.
Also, I don't see any reason not to take him out at lower levels and see how he holds up. The thing that concerns me most from the photos is the apparrent swelling and/or thickening in the fore ankles and suspensory area. So if I were conditioning him to event, I'd be a little obssesive about checking those areas for heat, swelling or any changes. I'd also probably be a little fanatical about leg care in general.
With his confo, ANY discipline is going to create wear and tear, eventing is just going to create it more quickly.
You can definitely see where he got his pasterns from! ;)
Sorry if I'm high-jacking the thread but I thought an acute angle on the pasterns was okay? I know you don't want very long and low ones but doesn't it provided a better shock-absorbing action than horses with very upright pasterns?
They are long and weak, not upright. I don't like upright pasterns especially for jumping, but this horse does have weak limb conformation. With upright pasterns, the weight gets jammed into the hoof. With long, weak pasterns, the weight gets shifted back and there's much more flex to the joint. http://www.stockphotopro.com/photo-thumbs-2/AEJ6K9.jpg This horse appears to have good pasterns, but see how much flex is in the frontmost hoof? Long, weak pasterns will flex even more. Doesn't mean he won't be useful - heck, he looks like quite the willing partner - just perhaps that you might have to be a little more neurotic with that aspect, and be on the lookout for any signs of injury or lameness.
