I'm getting my first mini soon and will need to make a decision about a cart. I'm an older but fit advanced rider who hasn't driven in 25 years. When I drove, I trained six of my dressage horses to drive and had lots of fun in a wire cart and then a Meadowbrook. I'm interested in eventually doing driven dressage and CDE with my mini, but mostly I'll be driving on my farm and in the surrounding state park. I love everything that I've watched and read about the hyperbike (the back support, the weight and the closeness to the horse) but worry that it might be too advanced a vehicle for me to start out with a new mini. Should I get a Kingston cart first and brush up? Are hyperbikes even acceptable for driven dressage? The new mini drives but has only done show driving and sulky work in the ring, so I'll be doing tons of long lining to accustom him to rough terrain.
