Mie; perhaps its easier for you, but do you know just how much pressure that bit puts in his mouth?
I know this wasn't directed at me but.... as long as you ride with the softest hands possible it shouldn't be a problem. If you have ride around the field pulling with all your strength to get the horse to slow down, well, the bit's not going to help you. But if the horse does get a little over-excited - which my guy has been known to do - you have the extra bit to help you out if needed.
And also, the horse will tell you. If you pull back on a 3-ring and end looking at your horse's forehead because they threw their head/neck up so high then it's safe to say you can move to a milder bit.
