Horse people always have an opinion. Driving is just as opinionated since many of us fight to keep the sport alive for generations to come.
I started out driving draft teams and was taught two handed and egads no whip. Ok Thomas you can get up off the floor now. Thankfully that was over 20 years ago, the boys were well trained, and I was alot younger. The last 15 years have been heavy into driving and I must say I drive two handed depending on the vehicle and or horses needs. I also drive coachman style and truely enjoy it. In fact with some guidance from Holly Thompson I was able to get my little gelding balanced, bending, doing circles, and figures of eight with coachman style. I was not brave enough to try the Tandem in figures just yet. The better position of being in a gig is most helpful for proper coachman style. I find it harder in roadcarts and meadowbrooks.
I have often commented to my trainer that I personally don’t care for the training vehicle we use as it hinders ones practice of proper driving. Since we work some days six singles they all seem to get put to it, as it’s easier then dragging out the carriages. I’ve also caught myself doing a bridge like riding on very long drives to support my upper body position.
I agree with GH the europeans have mastered driving coachman style and it is impressive and something to shoot for. Nothing is really right or wrong as long as it is safe and you are having a good time while learning something new.
Good luck.
