Re: If you don't feel that it's right then don't do it !!
We were always told at the Col.'s yard when taught to ride always leave 2 fingers gap under buckle of nose band and 4 fingers under the throat latch and have been doing this for the past 46 years, never had any problems with this advice as this must have been as it was in the Cavalry, if it works etc.
Yes, same here.
When we first had Grouse, my daughters horse, we tried a few different types of bit and nosebands, one of which was a borrowed crank noseband as it had been recommended by her instructor.
I have to say I thought it was awful, and Grouse hated it - it was so tight he could hardly move his jaw, let alone open his mouth, and although I know it could have been loosened we didn't go down that road and he ended up with a flash and three ring gag which he was absolutely fine with.
So yes, if your gut instinct says no, go with that feeling !!
