I am changing bits - should I stick to the same size I had before?

If you are changing to a different bit you might need to get a bigger or smaller one depending on what is being changed. 

1. Changing the cheekpiece: If you are curently in a fixed ring and changing to a loose ring, add 5mm to your bit size.  If you are using a loose ring and changing to a fixed ring, go down by 5mm.

3. Changing the mouthpiece:

  • If you are using a solid mouthpiece and changing to a semi-broken mouthpiece, add 5mm
  • If you are using a semi-broken mouthpiece, changing to a mouth piece with a single break, double break or flexi material add 5mm
  • If you are using a solid mouth piece and changing to a mouthpiece with a single break, double break or flexi material, add 10mm.

The reverse of the above would mean that you go down the equivalent size.

For example: If you were using a solid mouthpice with fixed cheek pieces (eg an eggbutt happy tongue) and changing to a loose ring bit with a double jointed mouthpiece (eg a NS Verbindend Loose Ring), you would add 15mm (half an inch) to your original size.  And vice versa, you would go down 15mm.
