So I am looking at getting a Myler bit and have been checking on how to measure so I can order online. I measured the bit he is in now and it says 5 but when I tried the whole twin in his mouth thing it said closer to 5.5. How do I get a true measurement? He really did not like me putting the twine in his mouth but he let me do it 2 times. (such a good guy).
So tell me what you think I should do?
