We are correcting a neg plantar angle which requires frequent trimming, but I'd like the horse to get some relief with wedges
First,before I offer his advice, I will say that I teach barefoot trimming, However I also teach when and if it is apppropriate. In this case, it is probably not appropriate. Frequent trimming can not correct the underlying cause of a negative palmer/plantar angle in the long run despite what some barefoot advocates try to claim. Most cases of NPA are due to a lack of internal support structure in the rear of the foot. There is no proof or evidence that frequent trimming actually builds cartilage, so trim all you want but you will not put cartilage in the foot.
If you want to solve your delimma, get him properly shod with wedges. PROPERLY shod would include frog support to keep the back of the foot healthy and stimulated, heels of the foot trimmed back enough before the shoes are applied, and breakover eased around the whole foot. Why bother with casting when you can shoe him for the same cost (maybe less) and it will be done and require no maintaince for the next two months.

We have managed to address the horse having underrun heels with the trimming, so I can see where I'm still in that mode. From the outside, the foot looks good.
I understand what you are saying about the shoeing and it makes sense to me. This is a young horse (4). Have you ever seen a case where proper shoeing in a young horse allowed the internal structures to improve?
