I know a wonderful breeder that has full and half clydes (Clyde/TB crosses). My boy is from there as are several horses owned by my clients, and they have wonderful temperaments, are extremely well bred (the owner shows a 6-hitch team), and excel as sporthorses as well. Feel free to PM me for more info. They are located in Nunda, NY, which is about 13h from you so while far, if you aren't finding anything in your area, I can't recommend these horses enough.
This is Duke, my boy, who stands at 17.3h:
Here is his father, a full Clyde stud (don't mind the mud, it had rained all night...)
And this is a Perch they have at their barn who is just breathtaking!
