Same here, I have used the split brakes by pushing forward on the cruise control with my left hand and split braking when pushing snow/ice on the driveway, it is about the only time I use them, ordinarily don't need the split brakes with a hydro, as you can reverse instantly and "see-saw" so easy with the hydro and the steering wheel for your sharp turning needs.
Some have "crossed over" and used their left foot for split braking duties, (the Kubota shuffle) and a few are nimble enough to use their right foot for both the hydro and the brake pedals.. Not me. It just isn't a big deal to me, and I have never cared for brakes on the left side. Some people left foot brake with an automobile also, but to me brakes belong on the right foot where my "muscle memory" thinks they are.
