Explain what you like/don't like about the bit.
What bits have you used?
On my show horse currently, I use a smooth snaffle at home, a square snaffle for pleasure, and a Pelham snaffle for equitation.
I have used a slow twist, eggbutt snaffle, twisted wire, kimberwicke, and a Myler.
The eggbutt made him loose hair and some skin. >.<
He HATED the slow twist and twisted wire.
The kimberwicke was too much and at the time my hands weren't steady enough.
And the Myler was good, but he likes the square snaffle better.
He is extremely soft mouthed and I have to be so light with him.
