Lessons learned
I’ve Hunted a “snaffle at home and for eventing” type of horse who totally blew me off in the Hunt field with a snaffle. The Wonder Bit worked great for him. I would also recommend a running martingale and flash noseband. Not all at once, but as building blocks to your system.
The goal of the day is for each of you to enjoy the Hunt and hounds. It will take a while, perhaps an entire season, to see how you both enjoy the Hunt. Whicker has good advice. It takes many seasons for a nice Hunt horse to evolve and there is no hurry.
